Cook and whisk about 7 minutes until mixture is slightly thickened. Add the dry ranch dressing packet, stir to combine.  Stir in 3 cups of grated cheese (you should have one cup of grated cheese left to sprinkle over casserole before baking). Whisk until cheese has melted.
    Place the sweet potato slices , cheese sauce, spinach and cooked chicken in a large bowl, toss gently to combine. Spoon into prepared baking dish. Sprinkle the top of the casserole with the remaining one cup grated cheese. Bake 25 -30 minutes or until cheese has melted and casserole is heated through. Let stand about 10 minutes before serving.
