Chicken, Mushroom, and Rice Casserole

Crystal ~


A nice versatile casserole using up left over chicken or turkey. You can adjust about anything in this recipe to suit your taste. I have used turkey, peas and carrots, and various cheeses in this recipe. However, I generally stick to using white or brown long grain rice because it has more flavor, nor as dry as instant rice, in my opinion. Prep time does not include cooking the chicken or rice.
