When I was a "Scout" we made these! We would peel the banana and cut a wedge in 4 places the length of the banana and fit a square of hershey's with a big marshmallow between the chocolate. These were placed in a foil pouch. It was such a treat!
This is a great pie that my mother made all the time - she would put apple pie filling in the mincemeat to cut the tartness and it made it more fantastic!
