I am definitely with the beer suggestion....but another is
Slice potatoes in 1/4 to 1/2 in layers, rub with olive oil or if available, like the Chief uses, bacon grease and salt and pepper to taste. Grill over the hot part of the fire until they are a little crisp on both sides then put on the "cool" side of the grill to finish cookig. 5 Minutes before the entree is done, cover with slices of your favorite cheese..I like provolone and pepper jack. Eat it like a steak.
Meat and Potatoes...cant go wrong!
