I don't know what to call this so choose the name "survival bread". I am looking for a recipe to make some kind of a bar - not a granola bar but about the same shape that has a shelf life of several months - I have a seal a meal type machine so can vacuum seal it. I have eaten some store bought products like this and they were something akin to a lump of sawdust. I will appreciate any ideas, as well as help with the real name of this kind of food so that I can google on it.
