I've had a really good meal but I can't remember the name. I'd like to say it's called "hobo dinner". yep, here are some different recipes I found.

The one I had and really enjoyed was a potato sliced open with ground beef and veggies on the inside. It's wrapped in aluminum foil and cooked over an open fire. I believe you have to bring a lot of the stuff along cooked already, so if you don't have a cooler this may not be the best meal.
