How to Make It
Preheat grill to medium (350°F to 400°F). With peel on, slice ends off banana, and cut in half lengthwise. Place banana halves, cut side up, in center of a piece of aluminum foil. Top with chopped chocolate, pineapple, and nuts. Close foil packet, and seal edges.
Place packet on grates, and grill until chocolate is melted and banana is heated but still firm, about 6 minutes. Open foil packet; top with ice cream, whipped cream, caramel sauce, and cherry. Enjoy immediately.
