Chop chicken up into tiny cubes and add to skillet with a tiny amount of oil. When chicken is done add all of the ingredients except the salsa, cheese, and red bell peppers. Simmer for 2 hours. Stir occasionally. If mixture begins to get dry add more chicken stock. Preheat oven to 350 degrees. Cut the tops off the peppers and clean out seeds and insides. Boil the peppers on the stove top for 3 minutes with salt. Drain and cool. Place peppers on a baking dish and spoon the mixture into the peppers. Top with salsa and cheese and bake for 30 minutes.
