Lightly grease a 12 cavity muffin tin. Place 2 Bridgford Parkerhouse Rolls in each cavity. Spoon ranch dressing on top of each roll to coat tops of rolls. Sprinkle evenly with Parmesan cheese. Let rise in warm area until double in size. Bake in a preheated 375° oven for 20 minutes or until lightly browned. Remove from oven and pan to cool on wire rack.
