eggs powdered milk butter potatoes flour brown rice (maybe ask for that precooked stuff that comes in the pouches that you only have to microwave, you can eat that raw if you have to) honey dried pinto beans canned tomatoes (in case we need to Macgyver some shit and cook in them, most of the stuff on this list can be cooked in some way or another that way, I'd think. If we do that we won't really need the precooked rice and can go for the regular stuff.)
If someone is willing to put the biggest container of salt we've got in the house on the list then we can make that last a while if we ration carefully. That will free up a slot for another vegetable. Maybe fresh spinach? It cooks easy, goes well with plain old eggs, you can toss it into a tomato sauce easy, eat it raw.
