PREPARATION:
- Prepare grill for direct cooking.
- Place bag in 1-inch deep baking pan. Combine marinara sauce, meatballs, bell pepper, olives, Italian seasoning and red pepper in large bowl. Spoon into bag, arranging in even layer. Double fold open side of bag, leaving head space for heat circulation.
- Slide bag off pan onto grill grid. Grill, covered, over medium-high coals 11 to 13 minutes or until meatballs are hot. Carefully open bag to allow steam to escape.
- Meanwhile, place two pieces cheese on bottom of each bun. Spoon meatball mixture into buns. Sprinkle with Parmesan cheese.
