One cool recipe for this (and any means of cooking, really) is cut the chicken, beef, whatever into small pieces, toss in some veggies (carrots,celery,onions,potatoes are favorites), along with a few slices of butter and whatever seasonings you like. Wrap it up well in aluminum foil, and toss it on the engine/fire. I recommend 2-3 sheets of foil if you can manage it, so the fluids don't leak out.
