There is nothing like a good tin foil dinner.  I peel my potatoes and dice them up along with some carrots then add a little onion flake and some ground beef.  Wrap in tin foil, then in damp newspaper or damp paper towels, then in tin foil again.  I bake at 375 for about 45 minutes or until done.  We still haven't done this camping out here yet but plan to someday, this is a good one to have in the fire while you set up camp.
