This is fun on a camping trip or at home on the BBQ grill.
Place a whole banana onto a sheet of aluminum foil. Using a sharp knife, cut the banana from end to end leaving the bottom of the peel (the bottom of the boat) uncut.
Spread the top of the peel and the banana open just enough to add some chocolate chips, marshmallows and crushed graham crackers.
Use the foil to seal closed the entire banana and toppings.
Put the wrapped banana on the campfire or on the grill for several minutes – just long enough for the marshmallows to melt. Remove the banana from the heat and unwrap the foil enough use the foil wrap as a plate.
Use a spoon to eat the banana and toppings out of the peel. Messy, but yummy!
