Food refrigeration options?

Any type of canned food will do you well in this situation. Canned fish, salmon, tuna, sardines, provided you use all of it. Canned corned beef, and canned ham,(small) or canned chicken can also be had. Apples, oranges, bananas and pears don't need refrigeration. Carrots, beets, potatos, tomatos and onions don't need to be cold. I think your best bet right now is to subsist on as many canned foodstuffs as you can manage. I'm not sure eggs are a good idea.
