In my case, I have a big chest freezer...so meat goes there. And frozen veggies. Microwave meals for really tired, quick eating days, if those are allowed.

Nuts, seeds, pasta would be high on my list. Tuna or other canned meats. Canned beans, and greens (I snack on a can of spinach or collards from the can when I feel too tired to do anything much but eat). Bread can freeze well, especially if you use for toast. Jarred or canned fruits, jellies, preserves.
