Have one of the seal-a-meal things. Would make a packet of chinese dish, chunks of chicken, pea pods, carrots, etc with spices, sauce in the package, then seal. Would make a day ahead of campout. Put rice in another package. When ready to eat, would boil a pan of water with both packets in water, unopened, to warm up the food. Works with spaghetti, cobbler, all kinds of things.
