Combine the ingredients for the meat mixture using a pastry blender. Form 12 meatballs with a large cookie scoop and place them in a baking dish. Mix the topping ingredients in a bowl. Then use a spoon to put sauce on each meatball until the sauce is gone. Cover the baking dish with foil and place it in the oven on the middle rack. Bake at 350 degrees for 45 minutes until the meatballs cook through, and the sauce is bubbly.
