Lightly grease a large baking sheet. Remove tray from package. Remove each log of 6 rolls from tray. Place each log of rolls on pan (you should have 3 logs of dough with 6 rolls in each log). (If using Bridgford Frozen Ready-Dough, let the dough thaw. Slice each loaf into 12 pieces, cutting only 1/2 of the way through the dough. Place on greased baking sheet.) Coat each log of dough with ranch dressing. Sprinkle with Parmesan cheese and garlic powder. Let the dough rise until double in size. Bake in a preheated 375° oven for 20 minutes. Remove from oven to cool on wire rack.
