If you read Doug's personal kit list, He's been packing and suggesting folded aluminum cooking pans too.
Look over that website and you will see a nice article on friend Oak Norton and SPARKLITE ( you can't boil it if you can't light it!)
Also notice under the suggested oven containers the folding cooker! These were a popular item made, I believe in Israel. Some legal issue stopped importation for many years.
Well, they seem to be back, I've found a retailer and am getting one to test..
