bananas marshmallows chocolate chips
Make a slit in the banana, lengthwise. The kids can put in a few marshmallows (fat free, I believe) and a few chips (or possibly leave out for fat free). Wrap in foil and heat for a few min by fire, sufficient to heat the marshmallows and chocolate. The kids can peel and eat them. Never got to try this with our scouts, but it sounds easy sufficient. They will also feel like they got to participate this way, too, by adding the marshmallows and chocolate chips.
