For each s'more, put together a graham cracker and chocolate square (from candy bar) the same size as the cracker. Toast marshmallows over embers until they are melty. Put two marshmallows on each cracker-chocolate combo, then cover with another graham cracker, and squish them together. If you don't have a campfire or barbecue handy, you can toast marshmallows over a gas range. Be sure to get your parent's permission first!
