Preheat oven to 375°F (190°C) for even baking and a golden crust.

Lightly flour your work surface and roll out the pizza dough into a 12 x 14 inch rectangle. For easier handling, roll directly onto parchment paper.
03 -
Mix 1 tablespoon of melted butter with minced garlic in a small bowl. Brush this mixture evenly over the entire surface of the dough.
04 -
Sprinkle ½ cup mozzarella over the dough, leaving a 1-2 inch border along one long edge and both short edges. Layer ham slices evenly, followed by another ½ cup mozzarella. Add salami and pepperoni layers, then top with remaining cheese.
05 -
Brush beaten egg along the exposed edges of the dough. Starting from the long edge without egg wash, roll the stromboli tightly jelly-roll style. Pinch the seam to seal and tuck the ends under.
06 -
Combine remaining 2 tablespoons melted butter with garlic powder, Parmesan cheese, and parsley. Brush this mixture over the top of the stromboli. Make shallow diagonal cuts about 2 inches apart across the top using a serrated knife.
07 -
Transfer the stromboli to a baking sheet or pizza stone. Bake for 25-30 minutes until the top is golden brown and crisp.

Allow to cool for 5 minutes before slicing into 8 pieces. Serve with warm marinara sauce for dipping.
