With the stem of the banana facing up, cut a slit in each banana leaving about 1/2 inch on each end uncut. Place a layer of chocolate in the slit and then a layer of marshmallows on top of that. Wrap in aluminum foil and heat on grill over a hot bed of coals until marshmallows and chocolate are melted.
Unwrap and enjoy!
If you are really adventurous, top them off with a scoop of your favorite ice cream and nuts and you have yourself a "to die for" banana split!
