Take small knife & split bananas on the inside curve, lengthwise about 2/3 of the way thru, (do this step for children) push banana kind of open.
Sprinkle a generous amount of brown sugar into fold
Next follow with a sprinkle of chocolate & peanut butter chips & mini marshmallows
Wrap in foil tightly so heat will stay inside & make bananas soft & melt ingredients. Place on grill for approximately 20-25 min till ingredients are warm & melty, you can also bake in preheated oven @ 350 degrees for 20 min. Enjoy!
