What NOT to do with it. As a household of two, roasting a chicken (or buying one at the grocery store) .... well, the point IS the leftovers. If all else fails (i.e., we get unexpected invitations to eat out or something), I pile the entire carcase, an onion, carrot, celery, thyme, sage into a pot, cover it with water, simmer, drain, freeze for soup use later.
