Green sticks or coat hangers (or Campfire forks)
Get prepared by getting 1 large graham cracker and breaking it in half. Cover 1/2 of the graham cracker with Hershey bar.
Put a marshmallow (or 2) on the stick and hold it over the fire until roasted. Some people like them lightly golden, others like to catch them on fire and then blow the fire out. If you do that, be careful. You have to put the fire out quickly or your marshmallow will fall on the ground. When the marshmallow's roasted, place on top of the Hershey bar, put the other graham cracker on top and bite down.
This is one of the best known camping recipes around, enjoy!
