What is claimed is: 1. A method for processing and storing a foodstuff in a metal container and subsequently heating the foodstuff in a microwave oven, comprising: providing a container comprising an end closure, a bottom portion and a metal sidewall positioned therebetween, said metal sidewall consisting of no microwave energy defusing coatings on an interior surface, said container having a height of at least about 2.0 inches, said bottom portion further comprising a microwave transparent portion with a cross-sectional area of at least about two square inches, filling said container with a foodstuff; sealing said end closure to said metal sidewall to create a substantially airtight seal; providing energy to said foodstuff to elevate the temperature of said foodstuff to a sufficient temperature for sterilization; storing the foodstuff in said container in a substantially hermetically sealed condition; removing said end closure of said container to create an open top to said container; and providing microwave energy to said foodstuff in the microwave oven prior to consumption by an end user, wherein the microwave energy travels through said microwave transparent material positioned on the bottom portion of the container and the open top of the container and reflects off of said interior surface of said non-coated metal sidewall, wherein the foodstuff positioned within an interior portion of the container heats faster than foodstuff positioned along the metal sidewall of the container. 2. The method of claim 1, wherein said end closure is comprised of a metal material. 3. The method of claim 1, further comprising selectively placing a microwave transparent lid over an upper portion of said sidewalls prior to providing microwave energy to said foodstuff to substantially eliminate splattering of said foodstuff. 4. The method of claim 3, wherein said lid has one or more apertures to facilitate the release of steam. 5. The method of claim 3, wherein said lid is comprised of a flexible plastic material. 6. The method of claim 3, wherein said sealing step comprises double seaming the metal sidewalls of said container to said end closure. 7. The method of claim 1, wherein said microwave transparent portion is comprised of at least one of a polypropylene, a polyethylene, and a multi-layered polypropylene/EVOH material. 8. The method of claim 1, wherein said bottom portion further comprises a substantially concentric shaped ring having a first end double seamed to said metal sidewalls of said container and a second end operably interconnected to said microwave transparent material. 9. The method of claim 1, further comprising the step of shipping said container and the foodstuff to a distribution center. 10. The method of claim 9, further comprising the step of stacking a plurality of said containers which are filled with the foodstuff to a height of at least about 4 feet prior to said shipping. 11. The method of claim 1, wherein providing energy to said foodstuff comprises placing said container and associated foodstuff in a steam bath having a temperature of at least about 140° F. 12. The method of claim 1, wherein said end closure of said container further comprises a pull tab for selectively removing at least a portion of said end closure from said container sidewalls. 13. The method of claim 1, wherein providing microwave energy in said microwave oven comprises elevating the temperature of the foodstuff positioned proximate to the center of the container prior to elevating the temperature of the foodstuff positioned proximate to an interior surface of said sidewall. 14. The method of claim 1, wherein said foodstuff comprise an edible solid, a liquid and a combination therein. 15. The method of claim 1, wherein said metal sidewall is comprised of at least one of a steel, an aluminum, a tin and combinations therein. 16. The method of claim 1, wherein said end closure further comprises a tamper resistant indicator, wherein a change of shape in said tamper resistant indicator identifies a change in internal pressure in the container. 17. The method of claim 16, wherein said tamper resistant indicator is a deflectable tab having a substantially concave cross-sectional geometric profile. 18. The method of claim 1, wherein the foodstuff is stored within said container in a vacuum. 19. The method of claim 1, wherein said metal sidewall further comprises a thermal insulation material interconnected to at least a portion an exterior surface of said metal sidewall. 20. The method of claim 19, wherein said thermal insulation material is comprised of at least one of a plastic material, a foam material, and a paper material. 21. The method of claim 1, wherein said metal sidewall is a formed sheet of tin material welded along a seam. 22. The method of claim 1, wherein the foodstuff stored in a 12 oz. container with an open top and a microwave transparent material of said microwave transparent portion positioned on the bottom portion can be heated to a temperature of at least about 140° F. in a time period no greater than five minutes in a 1,000 waif microwave oven.
