What can you cook on a campfire?

There's nothing quite satisfying (and in some cases, nostalgic) as throwing a potato into the hot ashes of a back garden campfire and waiting a very, very long 40 minutes for it to cook through. There's just nothing better than enjoying the fire's warmth while eating your freshly fire-roasted snack. We've heard of the usual campfire s'mores, sausages, and potatoes. What else is worth cooking on an open fire?
