Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
Divide the dough into 8-10 equal pieces.
Flatten each piece into a small disc (about 3-4 inches in diameter).
Spoon about 1-2 tsp pizza sauce in the center, then add some cheese and a few pepperoni slices.
Carefully pull the edges of the dough up around the filling, pinching and sealing the dough fully to make a ball.
Place each stuffed ball seam-side down on the baking sheet.
Brush the tops with either melted butter or beaten egg for a golden finish.
Sprinkle bagel seasoning (everything bagel seasoning or your favorite mix) on top.
Bake for about 18-22 minutes, or until golden brown and cooked through.
Let cool for 5 minutes before serving.
