5-gallon jugs, water coolers, and food mixes(boxes of seasoning and beans/dried veg/rice/pasta, just add to hot liquid/add hot liquid/add hot meat and enjoy.)
The first two would be easy, the first is just a new container, the second would probably just be a variation of a counter that contains some pipes, plastic chunks and possibly some electrical components when taken apart, and the final thing would probably be closest to MREs in functionality. Perhaps with the ability to read the box to learn how to cook the contents, then take apart the box into a normal cardboard box… (Have the box, take it apart to get ingredients and the box, still with writing on it, take that apart to get a normal box). Infact, the ability to read a box(or bag) to learn a recipe would in itself be an awesome feature, what with almost every food item in New England that comes in some packaging coming with a recipe…
