All of this cooking is makin' wax nostalgic (and hungry also). But, I remember back when I was in scouting we made "zip-packs". I don't remember the exact cooking times, but I do remember it was build your own from a number of ingredients. Potatoes, carrots, and burger patties (with a little salt and pepper) were my choices. There were onions, tomatoes and other things that I can't remember right now.

On the camping trip, it was the best darn meal of the weekend.
