Ground Beefm sometimes I add a bit of ground sausage. I always add Worstershire Sauce, eggs, uncooked oatmeal, or bread crumbs. onion garlic are always a must as well as egg. The surprise ingredient? grated apple! Makes is moist as can be! Ketchup spread on top and then uncooked bacon on top of that and it will cook along with the loaf. Delicious!
