Emergency food bars and sealed camping meals are really great to keep on hand for emergency evacuations. I personally keep a couple of days supply of both on hand and supplement my plan with my kitchen supplies.
Basically, I keep a duffle bag in my kitchen and a list of the extra staples, that I keep on hand. My list include canned soups, vegatables, and fruits. Also, cereals, crackers, pasta, and rice. Along with lots of peanut butter.
In addition, we have a freezer with lots of frozen food meals and some ice that we could all put in our cooler if need be.
I think this is a more sensible plan than going out and buying 25 cans of beans or MRE meals and sticking them in a box somewhere.
