1 pound elk burger, 1 pound hot italian ground sausage, throw in a large mixing bowl and add 2 eggs, 1/4 cup of milk, 2 packages of spaghetti seasoning, 1/4 cup parsley, 1 cup italian bread crumbs, 1/4 cup parmesan cheese. Mix well with hands. Roll a meatball and add a little cube of mozzarella in the middle of each meatball. Cook in crockpot on high with a couple cans of pasta sauce for 2 and a half hours. Pretty dang good!
