Pizza sauce, warmed or additional ranch salad dressing, optional
On a lightly floured surface, roll pizza dough into a 12-in. x 10-in. rectangle. Spread ranch dressing evenly to within 1/4 in. of edges. Sprinkle with cheese, pepperoni and onions. Roll up jelly-roll style, starting with a long side.
Cut into 1-in. slices. Place cut side down on a greased baking sheet. Bake at 425° for 10-13 minutes or until lightly browned. Serve warm with pizza sauce or additional ranch dressing if desired. Refrigerate leftovers.
