Manchurian noodles, 10 cents a package, seal in ziplocks... although they do need to be prepared.

Also, if you can do some planning... get a 8 or 12 oz. wide mouth sealable plastic container for liquids and put dried goods in it with proper amount of water, probaly prepare it after breakfast and it will be pre- hydrated by lunch, heat alittle if you want and ready to go...

You would need to pack dried goods for this like dried beans, rice, blackeyed peas, you know what I mean... all pretty cheap at the local grocery store...
