INSTRUCTIONS:
Prepare meatballs as directed on the package or for homemade meatballs, and combine all meatball ingredients.
Roll into 1″ balls and place on a parchment-lined pan. Bake at 350°F for 20 minutes or until cooked through.
Place cooked meatballs in a saucepan with pasta sauce and simmer covered 10 minutes.
Meanwhile, spread garlic butter inside each roll. Heat broiler and broil rolls until golden, about 3 minutes.
Arrange rolls in a 9×13 baking dish. Place 4 meatballs in each roll and top with a little bit of sauce and cheese.
Broil for 2-3 minutes or until cheese is melted. Serve with additional sauce for dipping if desired.
