In a crockpot place seasoned with salt and pepper chicken breasts. Place chopped onions on top of the chicken then pour in the cream of chicken soup and the chicken stock. Cook on low for 7-8 hours. Prepare the Rice Select Texmati rice as directed on back of the box. Then once chicken is cooked place on a plate and shred chicken. Then return chicken to the crockpot. Then mix in the rice corn and most of the cheese. I like to leave a little cheese out to sprinkle on the top. Mix well and keep in crockpot until cheese is melted over everything. Then Serve!
