The tray of claim 1, wherein the platform is a first platform of a pair of opposed platforms. 14. The tray of claim 13, wherein the platforms are separated by a recess. 15. The tray of claim 14, wherein a lowermost portion of the recess is substantially coplanar with the base. 16. The tray of claim 15, wherein the line of disruption extending substantially between the pair of points that lie along the peripheral edge is substantially perpendicular to the recess. 17. The tray of claim 1, further comprising a channel extending at least partially across the platform. 18. The tray of claim 17, wherein the channel comprises an indentation in the platform. 19. The tray of claim 17, wherein the channel is upwardly open. 20. The tray of claim 17, wherein the channel includes a lowermost portion that is elevated relative to the base. 21. The tray of claim 17, wherein the first portion of the platform has a first height relative to the base, andthe channel includes a lowermost portion having a second height relative to the base so that the lowermost portion of the channel is positioned above the base, wherein the second height is less than the first height, so that the lowermost portion of the channel is positioned between the base and the first portion of the platform. 22. The tray of claim 17, wherein the channel extends through the second portion of the platform. 23. The tray of claim 17, wherein the channel extends linearly at least partially across the platform. 24. The tray of claim 17, wherein the channel extends curvedly at least partially across the platform. 25. The tray of claim 17, wherein the channel is a first channel of a plurality of channels extending at least partially across the platform. 26. The tray of claim 25, wherein at least some channels of the plurality of channels are parallel to one another. 27. The tray of claim 25, wherein at least some channels of the plurality of channels are perpendicular to one another. 28. The tray of claim 1, wherein the microwave energy interactive material comprises a susceptor. 29. A microwave heating tray, comprising: a substantially planar base defining a peripheral margin of the tray, so that a peripheral edge of the base is a peripheral edge of the tray, wherein the base includes a line of disruption extending substantially across a portion of the base from a first point on the peripheral edge to a second point on the peripheral edge of the base, the line of disruption defining a handle portion of the base, wherein the handle portion of the base is operative for being moved relative to the base along the line of disruption; anda platform extending upwardly from the base, the platform including a heating surface that is elevated relative to the base, the heating surface including microwave energy interactive material, anda face that extends obliquely and downwardly from the heating surface to the base. 30. The tray of claim 29, wherein the platform is a first heating surface of a pair of opposed platforms, andthe opposed platforms are each substantially semi-circular in shape. 31. The tray of claim 30, wherein the opposed platforms are separated by a recess, anda lowermost portion of the recess comprises the base. 32. The tray of claim 31, wherein the line of disruption extending substantially across a portion of the base extends in a direction substantially transverse to the recess. 33. The tray of claim 29, further comprising an upwardly open channel extending at least partially across the platform, wherein the upwardly open channel includes a lowermost portion that is elevated relative to the base. 34. The tray of claim 29, wherein the peripheral edge is substantially circular in shape, so that the handle portion includes a substantially arcuate portion the peripheral edge of the base. 35. A microwave heating tray, comprising: a substantially planar base having a peripheral edge, wherein the peripheral edge of the base is a peripheral edge of the tray, the base including a guide for positioning the tray relative to another tray, wherein the guide is defined by a line of disruption extending across a portion of the base, wherein the guide is operative for being folded out of the plane of the base along the line of disruption; anda platform extending upwardly from the base, the platform including an uppermost portion that is elevated relative to the base, wherein the uppermost portion of the platform includes microwave energy interactive material. 36.
