Preheat waffle maker with lighlty greased grids to medium heat. Divide pizza crust into 4 pieces. On a lightly floured surface, roll out each piece to about a 6½-inch circle; then use a 6-inch cookie cutter or bowl to cut dough.

Spread 2 dough rounds each with 2 tablespoons pizza sauce. Top each with ½ cup shredded mozzarella and half package of pepperoni slices. Place remaining 2 dough circles on top; crimp edges to seal. Cook, one at a time, for 10 to 12 minutes or until golden brown.
