I buy the cheapest ground sausage I can find and cut them into thirds. I add the meat to hamburger for extra flavor, so even though yours are already cooked, I would use them the same way.
You can chop them and add to hamburger in meatloaf, spaghetti, chili, tacos, anywhere you use hamburger.
They could also be chopped up and added to a white sauce gravy for sausage gravy and served over toast points or biscuits. Cut into pieces and add to omelet or fritata.
Whole you can make breakfast sandwiches, sausage and egg on English muffins, sausage biscuits, with or without eggs. On a croissant.
I'd love to have your dilemma.
