I think the best option is to buy a food processor and ground your own. Chuck roast or beef stew meat is about $2/ lb. where I shop and by cutting all the fat off I can have virtually fat-free ground beef. It takes literally a few seconds to ground up a couple pounds. Makes great burgers.
It depends on how long it's been expired, don't take it too far; a while ago I found some protein I'd forgotten about, it was a couple years old. I figured I'd try it anyway and got seriously sick for about a day...
