Grilled Foil-Pack Cheesy Fries

Heat gas or charcoal grill to medium-high heat. Toss frozen French fries with melted butter. Tear off 2 (12-inch) lengths of Reynolds Wrap® Heavy Duty Foil to make foil boats. Place half of the fries in a single layer in the center of 1 piece of foil. Loosely fold foil around edges to form a boat, leaving large hole at top to allow steam to escape; repeat with remaining fries and foil. Place foil packets on grill over indirect heat. Cover grill; cook 20 to 30 minutes, stirring once, until fries are crispy and baked through. Top each packet with 2 slices cheese; cook about 2 minutes longer or until cheese is melted. Sprinkle with sliced green onions and bacon bits just before serving.
