Here is a snack I tried a couple of camping trips ago:
Add some chocolate chips, again you could substitute other types of chips here as well.
Wrap them up tight in foil. And put them on the fire pit. We had to rig up a grate with some blocks of wood and rocks. I didn't take a picture of that, it wasn't pretty ;) One of those hanging grates on a tripod or other such set up would be wonderful for this.
What type of snacks do you enjoy while relaxing in the beautiful outdoors?
