When I was a kid (back before cub/Boy Scouts got turned pink/P.C.) our scout leader was a Vietnam veteran.

I remember one hike he showed us how to make two small pan fish we caught feed all 5 of us. While one person fished, the rest of us gathered wild roots. Dandilion roots, wild onion, cattail roots... Several other ones that the years won't let me recall. The fish were gutted and headed. Roots chopped up. Some leaves he had picked and identified for us were chopped and added to the mixture of roots. This was put on a large piece of anuminum foil, fish sat on top, then wrapped up. This was sat on a pile of coals to cook while we set up camp and tended to other things.

Eventually it was ready. I remember how good it tasted, and how he really did feed all of us with two pan fish!
