Parmesan Crusted Chicken Ranch Dressing (Hidden Valley Packet) - the buttermilk recipe is just like Longhorns. Do not use the bottle kind - it is not the same. Mix with parmesan cheese that is in the can - Kraft is fine. Not to thick and not to thin. Grill your chicken - put a good thick coating of parm sauce and then put a piece of provolone cheese on top. Broil it until it is browned.
