Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside. Lightly flour the work surface. Rest pizza dough in the center for 10 minutes to relax gluten. Roll dough into a 10 by 14-inch rectangle, maintaining even thickness. Brush surface lightly with olive oil to protect against moisture from the filling.

Arrange sliced ham evenly over the rolled dough, leaving a 1-inch border on all sides. Sprinkle mozzarella cheese evenly atop the ham. Season with garlic powder, dried oregano, salt, and pepper. Avoid excessive filling to prevent tearing during rolling. For extra flavor, scatter Parmesan cheese lightly over the top.

Starting on a long edge, roll the dough tightly into a log, jelly roll style, keeping the filling centered. Pinch the seam firmly to seal and tuck in the ends underneath. Transfer the rolled stromboli seam-side down onto the prepared baking sheet.

With a pastry brush, coat the top of the stromboli evenly with the beaten egg for a glossy finish. If desired, sprinkle a small amount of Parmesan cheese over the top. Using a sharp knife, score 3 to 4 shallow diagonal cuts across the surface to allow steam to escape.

Place the baking sheet on the center rack of the oven and bake for 20 to 25 minutes until golden brown and firm. Rotate the pan halfway for even browning. Bake until the internal temperature registers approximately 190°F. Once baked, transfer to a cooling rack and rest for 10 minutes.

After cooling slightly, cut the stromboli into thick slices using a sharp knife or pizza cutter to reveal distinct layers. Serve plain or with marinara sauce, ideal for lunch, dinner, or entertaining.
