Place 12 dinner rolls on a large baking sheet that has been sprayed with baking spray or line with waxed paper. Thaw rolls until soft, but still cold.
Preheat waffle maker and spray with cooking spray or brush with shortening. Roll each thawed dinner roll into a 4 inch flat circle.
Add 3-4 pepperoni slices and 2 tablespoons mozzarella cheese on top. Add another flattened dinner roll on top and press the edges a bit to seal.
Place one dinner roll on the center of the waffle maker. Close lid pressing down firmly, but not too much and cook for 3 -4 minutes or until the waffles are golden brown.
Repeat with the remaining filled dinner rolls. Cool slightly and serve with pizza sauce and ranch dressing.
Prep time: 30 minutes
Cook's Note: For toddler size pizza waffles which are perfect for little hands, cut one thawed dinner roll in half making smaller pizza dough rounds.
