Are you down to the last bit of turkey yet? Don't toss the carcass. Break it up and put it in a large pot and boil it until the tiny bits of meat start falling off. Remove the bones and strain the broth, then pick out the meat and freeze it for later. Cover some of it with the broth and you'll have a soup almost ready to go - just add rice and/or vegetables. Freeze some by itself, too. It's good for salads and sandwiches.
Boiling it is the only way to get it all, so if you haven't done this in the past, you may be surprised at how much more meat you can get - and how many very, very frugal meals you can make of it.
