One book I read suggested canned beans over dried for emergencies... because canned beans do not need to be soaked/cooked for a long time in a lot of precious water.

Also, nuts and nut butters, while useful may not be an option because of allerges.

Also, (speaking of nuts) please enjoy this video about a peanut oil mousetrap: https://m.youtube.com/watch?v=BxxFNkNf6q8
