12 (2-1/2 inch) graham cracker squares, made into coarse crumbs 3 cups (3 medium) sliced bananas 1/4 cup (1 ounce) mini chocolate chips 1/2 cup (1 ounce) miniature marshmallows
Cut 6 (18-inch) pieces of heavy duty aluminum foil. Evenly layer graham cracker pieces and bananas in center of each piece of foil. Sprinkle chocolate chips and marshmallows evenly over top. Wrap and double seal each bundle. Cook over a low grill for 2 to 3 minutes, turning once.
HINT: A self-seal sandwich bag works great for crushing graham crackers.
