The Red Ferret has an article on a device that I'm unlikely to ever use, since I don't own a car, but which could be of value on your next trip into the great outdoors.
The WaveBox portable microwave oven sells for $US199 and runs off a car cigarette lighter socket.
Unfortunately, the web page for the product seems to be down, so I can't provide any details regarding how powerful the oven is.
