I completely agree. Canned goods, preferably some that can be eaten without warming up, because you may need to save heating and cooling powers for a time if the power goes off. In the winter and there is a snow storm that causes the power to go out, you always have the snow and cold to help preserve your food supply, but what do you do in the summer? Water, bread if it can be somehow preserved, canned goods and things that don't need heating up like spaghetti o-s, beans, fruit, tuna fish, etc. Peanut Butter is a great protein provider. and make sure you have a manual can opener. That will not be gourmet dining, but, this is survival not a visit to Trump Tower.
Edited for an added question.... Someplace in the back of my mind, I seem to remember that there was some type of canned bread. It's a very vague memory and it might have been some type of novelty bread. Does anyone else remember anything like that?
