The method of claim 1, wherein the microwave energy interactive material of the second panel is positioned such that when the package is reconfigured into a second configuration inverted from the first configuration, the microwave energy interactive material is adjacent to at least a portion of the surface of the food item intended to be browned and/or crisped. 3. The method of claim 1, wherein the package further includes an opening for accessing the food item, andthe method further comprises at least partially obstructing the opening. 4. The method of claim 3, wherein at least partially obstructing the opening comprises activating a locking feature of the package. 5. The method of claim 4, wherein the package further includes a third panel joining the first panel and the second panel, andthe locking feature is defined by a line of weakening in the third panel and at least one of the first panel and the second panel. 6. The method of claim 1, wherein the food item is contained within a container, andinserting the food item into the package comprises inserting the container into the package. 7. The method of claim 6, further comprising securing the container within the package. 8. A method comprising: obtaining a package including a plurality of adjoined panels defining a cavity, the plurality of panels including a first main panel comprising a viewing window, anda second main panel in an opposed, facing relation to the first main panel, the second main panel including microwave energy interactive material operative for converting microwave energy into heat; andinserting a food item into the cavity of the package, the food item including at least one surface intended to be browned and/or crisped, the food item being inserted into the cavity such that the transparent viewing window displays at least a portion of the surface of the food item intended to be browned and/or crisped. 9. The method of claim 8, wherein the surface of the food item intended to be browned and/or crisped is an upper surface of the food item. 10. The method of claim 9, wherein prior to heating the food item in a microwave oven, the package is for being inverted to bring the microwave energy interactive material into proximity with the upper surface of the food item. 11. The method of claim 8, wherein the package further includes at least one open end, anda locking feature for at least partially closing the open end, andthe method further comprises activating the locking feature to at least partially obstruct the open end. 12. The method of claim 11, wherein the plurality of adjoined panels further includes a side panel extending between the first main panel and the second main panel, andthe locking feature comprises a portion of the first main panel and a portion of the side panel. 13. The method of claim 12, wherein the locking feature is defined by a line of weakening in both the first main panel and the side panel. 14. The method of claim 12, wherein the first main panel is joined to the side panel along a fold line, andthe locking feature comprises a slit extending from the first main panel across the fold line into the side panel. 15. The method of claim 14, wherein activating the locking feature comprises moving the locking feature towards the cavity along the fold line. 16. The method of claim 8, wherein the plurality of adjoined panels further includes a first side panel and a second side panel opposite one another,at least a first slit extends continuously through the first main panel and the first side panel,at least a second slit extends continuously though the first main panel and the second side panel,the first slit and the second slit each define a respective locking feature for securing a tray within the cavity, andthe method further comprises urging the locking features towards the cavity to secure the food item in the package. 17. A method comprising: obtaining a package containing a food item, the food item including at least one surface intended to be browned and/or crisped, the package including a first panel comprising a transparent viewing window through which the surface of the food item intended to be browned and/or crisped can be viewed, anda second panel opposite the first panel, the second panel comprising a microwave energy interactive material operative for converting microwave energy to thermal energy;removing the food item from the package;inverting the package;reinserting the food item in the package such that the microwave energy interactive material is adjacent to the surface of the food item intended to be browned and/or crisped; andexposing the food item to microwave energy, such that the microwave energy interactive material converts microwave energy to thermal energy and at least partially browns and/or crisps the surface of the food item intended to be browned and/or crisped. 18. The method of claim 17, wherein the surface of the food item intended to be browned and/or crisped is a top surface of the food item, such that reinserting the food item into the package causes the microwave energy interactive material to overlie the top surface of the food item. 19. A method comprising: opening a package containing a food item, the food item including at least one surface intended to be browned and/or crisped, the package including a first main panel comprising a viewing window through which the surface of the food item intended to be browned and/or crisped is visible, anda second main panel in an opposed, facing relation to the first main panel, the second main panel including a microwave energy interactive material operative for converting microwave energy into heat; andremoving the food item from the package;inverting the package;reinserting the food item in the package such that the microwave energy interactive material is adjacent to the surface of the food item intended to be browned and/or crisped; andexposing the food item to microwave energy such that the microwave energy interactive material converts microwave energy to thermal energy and at least partially browns and/or crisps the surface of the food item intended to be browned and/or crisped. 20. The method of claim 19, wherein the surface of the food item intended to be browned and/or crisped is a top surface of the food item, such that prior to removing the food item from the package, the viewing window overlies the top surface of the food item, andafter inverting the package and reinserting the food item into the package, the viewing window underlies the food item and the microwave energy interactive material overlies the food item. 21. A method comprising: forming a package including a plurality of adjoined panels defining a space for receiving a food item, the food item including at least one surface intended to be browned and/or crisped, the plurality of panels including a first panel comprising a transparent viewing window, anda second panel opposite the first panel, the second panel comprising a microwave energy interactive material operative for converting microwave energy to thermal energy,wherein the window is for displaying the surface of the food item intended to be browned and/or crisped when the package is in a first configuration, andthe microwave energy interactive material is for browning and/or crisping the surface of the food item intended to be browned and/or crisped with the package in a second configuration inverted from the first configuration. 22. The method of claim 21, further comprising positioning the microwave energy interactive material of the second panel such that when the package is reconfigured into the second configuration, the microwave energy interactive material is adjacent to at least a portion of the surface of the food item intended to be browned and/or crisped. 23. A method comprising: forming a package including a plurality of adjoined panels defining a cavity for receiving a food item, the food item including at least one surface intended to be browned and/or crisped, the plurality of panels including a first main panel comprising a viewing window positioned to display at least a portion of the surface of the food item intended to be browned and/or crisped, with the package in a first configuration, anda second main panel in an opposed, facing relation to the first main panel, the second main panel including a microwave energy interactive material positioned to be aligned with at least a portion of the surface of the food item intended to be browned and/or crisped, with the package in a second, inverted configuration,wherein the microwave energy interactive material of the second main panel comprises a susceptor that generates heat when exposed to microwave energy.
