Preheat Oven:

Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

Roll the Dough:

Roll out the pizza dough into a 10x14-inch rectangle on a lightly floured surface.

Add Garlic Butter Base:

Brush the dough with melted butter mixed with garlic powder and Italian seasoning.

Layer the Fillings:

Layer meats and cheeses evenly, leaving a 1-inch border around the edges. Add optional veggies or sauce sparingly to avoid sogginess.

Roll It Up:

Starting from the long side, roll the dough tightly into a log. Tuck in the edges as you roll.

Seal and Top:

Place the stromboli seam-side down on the baking sheet. Brush with the beaten egg and sprinkle with additional Italian seasoning. Cut 3-4 slits on top to release steam.

Bake:

Bake for 25-30 minutes, or until the stromboli is golden brown and crisp.

Cool and Slice:

Let cool for 5 minutes before slicing into 1-inch thick pieces. Serve with marinara sauce for dipping.
