In a large bowl, mix together cheddar cheese, salt, pepper, peas, carrots, corn, sour cream (or yogurt), cream of chicken soup, milk, and shredded chicken.
Spread the mixture evenly over the hash browns in the baking dish.
Sprinkle the top with bread
Bake in the oven for 1 hour, or until the top is golden brown and bubbly.
