In a large bowl, mix together the cream of chicken soup, milk, garlic powder, salt, and pepper.
Add the chicken, broccoli, and rice to the bowl, and stir until everything is well coated.
Transfer the mixture to a baking dish and top with shredded cheddar cheese.
Bake for 25 minutes or until the chicken is cooked through and cheese is bubbly.
Serve
Dish it up and enjoy straight from the pan, maybe with a sprinkle of extra cheese on top!
