Preheat oven at 435 degrees F (220 degrees C). Grease a glass casserole dish with olive oil or cooking spray.
Combine the chicken, spices, water, salsa corn and beans in the casserole dish and bake for 30-40 minute or until chicken is thoroughly cooked.
While the chicken is baking, cook the rice as instructed on the package (usually it takes 2 cups of water for every cup of rice).
After the chicken is cooked through, remove the breasts from casserole dish onto a cutting board and shred with two forks. Return shredded chicken to casserole dish and mix with the other baked ingredients.
Serve by spooning cooked rice into a bowl and topping with chicken mixture. Garnish with shredded cheese, a small scoop of sour cream (optional), green onions and cilantro.
