This site has some awesome camping dinner ideas. My favorites are always the foil packs. Everyone can put together their own and as long as it's completely sealed it's easy to cook. Will have to try some of these this summer.
Grilled cabbage. If you have never had it grilled you are missing out! Cut a head into 4~6 peices, put each on a piece of foil add a couple spoonfuls of butter, and top with bacon if desired. I also season it with season salt.
