Boil the chicken breasts for 20 minutes and then cut into 1/2 inch cubes. In a large bowl mix all of the ingredients, except for 1 pound of Shredded Cheddar Cheese. Place the mixture in a large glass baking dish, and sprinkle the remaining pound of Shredded Cheddar Cheese on the top.
Preheat oven to 350 degrees F. Bake for 60 minutes or until the topping on the cheese bubbles. Remove from oven and let stand for 15 minutes to allow the cheese to congeal before serving.
