With ET having a gluten and tomato allergy it does make it quite a bit more difficult for him to have stocked safe food supplies for her to eat. Wheat is hidden in virtually everything these days and buying gluten free things to eat is way more expensive than non gluten free items. Much harder to survive on peanut butter and crackers or tuna sandwiches with an allergy.

Think in terms of three meals per day, plus snacks you probably can't stock too many cookies and other treats, especially if you have children to feed.

2. Shelf-stable milk. While you can eat your cereal without milk, you'll certainly prefer to have it the regular way. If you consume dairy, you can find shelf-stable cow's milk in most stores. If, on the other hand, you prefer soy milk, nut milk or rice milk, it's possible your usual selection already is shelf-stable. Get plenty.

3. Hard cheeses. Although cheese should be refrigerated under normal circumstances, hard cheeses Swiss, cheddar and Gouda, for example last for several days or longer without refrigeration. Hikers report they do just fine with cheese on days-long hikes in very warm conditions. If you can handle dairy, cheese could be a good source of safe calories for you in an emergency.

4. Canned or boxed gluten-free soups. We're fortunate that many soup manufacturers now make safe products for us to consume.
Look for soups that are ready-to-eat (as opposed to those that need water added), since in a pinch you can eat them cold. Oh, and don't forget a clean can opener for your emergency kit.

5. Canned meat, chicken or fish. If you eat meat, these can provide some quick protein, even cold.
6. Dried fruit and nuts, plus chocolate. If you don't eat meat, nuts and nut butters can get you that needed protein, while dried fruit is a reasonably healthy snack that keeps for months. And of course chocolate is an essential food for any emergency.
