I did this when I was backpacking in Cali. above Camarillo in the hills. We just used a barbaque rack and held it at a decent distance, it cooked great for us, although we did burn the crust a little on the edges.
I did a 2 week backpacking trip through the Sierra Nevada Mountains and we had to carry our own food. We bought all freeze dried foods, spices, vegies, etc. It actually wasn't half bad for weighing 10lbs for 2 weeks worth.
I purchased my last cook book about 3 months ago. I purchased it at a regular book store by recommendation so its nothing against the forum, its just how I was turned onto cooking. I'll have to check out the amazon referrals though, thanks for the names and links everybody.
