These crowd-pleasing sandwiches are great when you're hosting a holiday open house or progressive dinner. Keep the meatballs warm in a slow cooker on your buffet table, and guests can serve themselves as they arrive.


  • 1 egg, lightly beaten
  • 1/2 cup milk
  • 1/2 cup dry bread crumbs
  • 1/4 cup finely chopped onion
  • 1/2 teaspoon salt
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon pepper
  • 1-1/2 pounds ground beef
  • 1 large onion, chopped
  • 2 tablespoons canola oil
  • 2 garlic cloves, minced
  • 3 cups water
  • 1 can (12 ounces) tomato paste
  • 2 teaspoons salt
  • 1 teaspoon sugar
  • 1 teaspoon dried oregano
  • 1/4 teaspoon pepper
  • 1 bay leaf
  • 14 submarine buns (6 inches each), split
  • 1-3/4 cups shredded part-skim mozzarella cheese


  1. In a large bowl, combine the egg, milk, bread crumbs, onion, salt, garlic powder and pepper. Crumble beef over mixture and mix well. Shape into 1-1/2-in. balls. Place on a greased rack in a shallow baking pan. Bake, uncovered, at 350° for 30-35 minutes or until no longer pink. Drain on paper towels.
  2. Meanwhile, for sauce, in a Dutch oven, saute onion in oil for 3-4 minutes or until tender. Add garlic; cook 1 minute longer. Stir in the water, tomato paste, salt, sugar, oregano, pepper and bay leaf. Bring to a boil. Add the meatballs. Reduce heat; simmer, uncovered, for 10-15 minutes or until heated through.
  3. Discard bay leaf. Spoon five meatballs with sauce onto each bun bottom. Sprinkle with cheese. Replace tops.
