Another good one, we called it 'hobo meal' growing up. You chop up potatoes and whatever schmeat and veggies you have. Throw it in tinfoil. Cover it in camping oil, salt, spices, and ketchup and mustard. Close it up and put it in a fire for a while until its done.

I also used to bring packets of this as a treat for the crew when I did controlled burns and reached a new level of crunchiness heretofore unknown to formerly-urban whitekind.
