This comforting casserole is a great way to use up leftover rotisserie chicken. Simply shred the chicken and mix it with some cooked rice, cream of mushroom soup, and some veggies, such as peas and carrots. Place it in a baking dish and bake it in the oven until it's hot and bubbly. You can also add some cheese on top for extra flavor. Serve it with some green beans or a side salad for a hearty and satisfying meal.
