How to Make It
Preheat grill to low (300°F to 350°F). Cut 6 (12-inch) square pieces of heavy-duty aluminum foil.
Cut each banana lengthwise along inside curve, cutting to but not through bottom peel. Open slit carefully to form a pocket. Crimp and shape a piece of aluminum foil around each banana, forming a boat.
Fill each banana with toppings of your choice.
Grill bananas, covered with grill lid, until bananas are heated through and candy toppings are melted, 12 to 15 minutes.
