Best hard-times food?

Easy, and I oughta know, I subsisted on the stuff for over a year:

Cooked cornmeal mush, with cooked beans, and anything and everything else mixed in.

Doesn’t take much to fill you up, makes a more or less complete protein, and, with some meat scraps and/or the occasional egg, makes a satisfying hard-times meal. Cost? Pennies per pound.
