In a large bowl, combine the chicken, chiles, soup, cheese, onions, salt, pepper and water and pour the mixture into a microwave safe 9x13 inch casserole dish.
Add the rice. The mixture should be the consistency of soupy pancake batter.
Cover the dish with a lid or plastic wrap and microwave for about 15 minutes (depending on the microwave). Serve with mexicorn and green salad if desired.
