Prepare meatballs according to package instructions.
In a large saucepan, cook and stir sauce ingredients over medium heat until well combined. Stir in meatballs; heat through.
Serve meatballs on sliced Party Potato Rolls, with toothpick or rosemary sprig through the top roll to keep it attached. (You may have meatballs remaining—serve plain with toothpicks or on additional Party Potato Rolls.)
