I am personally very proud of my restraint for saving the last box of Thin Mint Girl Scout cookies in the freezer until we went camping. I didn't hear about this idea until after this year's cookie sale was over. Next year I will buy a (or a few) box(es) to save just for this reason.
and campfire :)
Toast the marshmallow over the campfire as you normally would for S'mores.
