Boil the little dab of meat off of them and cook the marrow out. Makes for great soup. I have a fried that collects all of the beef bones from the cabin. He boils them down for the broth. There is an entire science to cooking with bones. My chief exposure to bone cooking was using the ham bone in a pot of beans. It adds a tremendous amount of flavor. Pig knuckles in navy peas is a great example.
