Spray counter lightly with non-stick cooking spray. Combine dinner rolls and roll into a football shape, 17-inches long and 12-inches wide.
Place on a sprayed baking pan. Poke several times with a fork to prevent bubbles from forming.
Pre-bake at 350°F 10-12 minutes. Allow to cool and then top with sauce and cheese. Place pepperoni in the center of the pizza in a smaller football shape.
Slice the string cheese lengthwise into fourths to form the laces and arrange on top of the pepperoni.
Bake an additional 10-13 minutes.
