I also subscribe to the foil oven technique for all camping food. This means you don't need any grates or pots and nothing to clean.
Individual chicken breasts in a doubled foil pouch with some BBQ sauce or Lawry's marinade of choice. Throw it in the coals for 5-10 minutes.
Steak, shishkabob style with bacon as mentioned.
Kielbasa and Brats on a stick are awesome.
You can wrap baking potatoes in doulbed foil and throw them in the coals. Takes about 25 minutes.
I also do single portion mixed veggies like that. A few drops of water and a pat of butter steams them nicely right in the foil.
Oh, marinated shrimp are also awesome this way... 3-4 minutes is all it takes.
