Preheat to 400°F (200°C) and line a baking sheet with parchment paper.

Roll the pizza dough on a floured surface into a ¼-inch-thick rectangle. Cut into four equal squares (or circles).

Spread 2–3 tbsp pizza sauce on one half of each piece, leaving a border. Add mozzarella, a few pepperoni slices, and a pinch of Italian seasoning.

Fold over the dough to form pockets. Press the edges to seal, then crimp with a fork.

Place on the baking sheet. Brush tops with olive oil and beaten egg. Sprinkle with salt and pepper if desired.

Bake for 15–20 minutes until golden brown and crisp. Check the bottom for doneness.

Let rest 5 minutes before serving. Enjoy warm with extra pizza sauce for dipping.
