Place rice in bottom of lightly greased 3 litre casserole dish, I sprayed the dish with veggie spray.
Combine tomatoes, garlic, onion,jalapeno pepper, chili powder and water in medium bowl; stir well. Pour half the tomato mixture over the rice; arrange chicken pieces on top of tomato layer and top with remaining tomato mixture; top with cilantro.
Bake, covered, in 325f degree oven for 1 1/2 hours until chicken and rice is cooked and all liquid is absorbed. Garnish with more cilantro if you wish.
