re: What to do with deer sausage

You can remove the casing from the sausage before and chop up the inside and add to other meat. I like smoked sausage mixed into venison burgers, rotel dip, omelets, etc.

Italian sausage of course for spaghetti.

red/white beans as mentioned are next level with a good smoked sausage.

I once did a jambalaya with all wild meat.
deer Smoked sausage, green onion, fresh sausage,backsrap cutlets, wild turkey, wild hog. There was not much left over.
