You need to specify what kind of camping. Car camping without consern for weight, I like to make this:
Potatoes
Onion
Butter
Salt/Pepper/You can get fancy , but you're camping so don't.
Cut up your onion and potato, then get a sheet of tinfoil big enough to make a pouch for it. With the shiny side up, coat the fucker in butter, then put in your shit with another lb (exaggeration

) of butter. Next do a russian doll type act with 16 more layers of tinfoil(I think I used 12 last time).
Put the fucker in or around the fire, and play with it for 30-45 minutes, or until it starts to get flimsy.
Also, if you have a BBQ taking the grill off that is good for putting over some coals for steaks and the likes.
But the number one rule is you really don't want to cook that often because cleaning up is a bitch unless you're in a camper/trailer.
Oh, and finally, you can't go wrong with beer
