Giant Meatball Sub Recipe

In a large bowl, combine the eggs, milk, onion, garlic, bread crumbs, salt and Italian seasoning. Crumble sausage and beef over mixture; mix well. Shape into 1-in. balls. Place meatballs on a greased rack in a shallow baking pan. Bake at 425 ° for 15 minutes or until browned; drain. In a Dutch oven, heat the spaghetti sauce over medium heat. Add meatballs; simmer for 15 minutes. Meanwhile, bake bread at 325 ° for 10 minutes or until heated through. Place mozzarella cheese on bottom half of bread; spoon meatballs onto cheese. Replace top. Slice sandwich into serving-size portions; serve with extra spaghetti sauce and, if desired, Parmesan cheese.
