I learned this one years ago in Girls Scouts and my boys love it. You take a banana and peel back just one part of it and scoop out some from the middle. Kind of resembles a canoe when you're done. Then you take chocalate chips and mini marshmallow and alternate them where you scooped out the middle. Put the peel back over the top and wrap in foil and stick in the coals for a few minutes and you have a neat desert and something the kids will love.
