The pizza was done in a reflector oven. There's a horizontal panel to support the food, a 45-degree lower panel to reflect heat upward into the food, and a 45-degree panel to reflect heat downward into the food. And then there's some wirework to keep it upright next to your fire. It all folds flat and slides into the pocket of your pack normally reserved for the ballistic armor plate. Maybe it isn't designed for that, but few other things would fit in there. Maps, perhaps? There may be another way to rig the reflectors to reconfigure as a solar oven.
