Cook the bags of rice until done about 10 minutes. Drain and let it sit for about 15 minutes or until cooled.
Put the rice into a medium sized baking dish. Mix the soup, milk, and the broccoli, 1/2 the bag of cheese and the salt and pepper (optional) until well blended. Sprinkle the rest of the cheese over the top of the casserole.
Bake in a 350 degrees F oven until lightly golden brown and bubbly and serve.
