This chicken and rice casserole is a meal in one dish, perfect for a busy family. It also makes a nice dish to take along to a dinner or potluck event. Serve this chicken casserole with a tossed salad or sliced tomatoes and warm rolls or biscuits for a fabulous busy day meal. We poached chicken breasts in a little chicken broth, but you could also use a rotisserie chicken to make this even quicker.
