This is an excellent resource on food storage from the Mormons; they're masters of the subject.
LDS Food storage
In the right-hand pane, especially check out the "Dry Pack Handouts" which will lead you to a comprehensive PDF that details storage methods (they are moving to mylar pouches over canning), types of foods to store, storage lifespan, and critically, recipes on how to use the stuff.
The foods they recommend are inexpensive bulk items that can be turned into a variety of meals using the included recipes. I certainly wouldn't want all of my "insurance" food to be bulk, but it's a good, inexpensive way to extend your food stores.
