If you had the facilities and time to do this as a break in your AW game it would be fun to present the table with a bunch of canned food -- labels removed and appropriately dented, and let your friends cook the meal on an open fire in the back yard.
Just make sure the denting is done just prior to game. Purchasing dented cans can lead to botulism poisoning.... unless that's the kind of realism you're going for!
