Total Time

Prep/Total Time: 30 min.

  • 1 package (12 ounces) frozen fully cooked Italian meatballs
  • 4 slices sourdough bread
  • 1-1/2 teaspoons olive oil
  • 1 garlic clove, halved
  • 1-1/2 cups pasta sauce with mushrooms
  • 1/2 cup shredded part-skim mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese, divided


  1. Preheat broiler. Microwave meatballs, covered, on high until heated through, 4-6 minutes. Meanwhile, place bread on an ungreased baking sheet; brush 1 side of bread with oil. Broil 4-6 in. from heat until golden brown, 1-2 minutes. Rub bread with cut surface of garlic; discard garlic. Tear bread into bite-sized pieces; transfer to a greased 11x7-in. baking dish. Reduce oven setting to 350°.
  2. Add pasta sauce, 1/4 cup mozzarella cheese and 1/4 cup Parmesan cheese to meatballs; toss to combine. Pour mixture over bread pieces; sprinkle with remaining cheeses. Bake, uncovered, until cheeses are melted, 15-18 minutes.
