Well, you have to have s'mores! I like to use different types of chocolate -- like Carmellos or Butterfinger squares . . . to spice it up a bit. We also poke pieces of summer sausage and grill it over the fire, remove it with a bit of cheese -- Scooby Snacks. AND use a thick dowl (sp?) rod and wrap a canned biscuit around and toast over the fire, pull it off and fill with squeeze butter and jelly -- slugs.
Not necessarily cheap or a meal -- but lots of fun.
