I'm spending the winter in Utah, being a ski bum. Consequently I'm broke, and can't eat out all the time, especially not at over-priced on-the-mountain restaurants.

I'm finding myself eating sandwiches every day for lunch, when what I really want is a warm meal. But I have no way of heating anything up, short of putting a plate on top of the engine and waiting.

Is there such a thing as a food warmer that can be plugged into the lighter outlet in my truck?

Many thanks for all your suggestions...
