Begin by setting your oven to 375°F (190°C) to preheat while you prepare the stromboli.

On a lightly floured surface, roll the pizza dough into a 12×14-inch rectangle.
03 -
Mix 1 tablespoon of melted butter with the minced garlic and brush the mixture evenly over the flattened dough.
04 -
Spread ½ cup of mozzarella cheese on the dough, place the ham slices evenly, add another ½ cup of mozzarella cheese, then layer with salami, pepperoni, and the remaining mozzarella cheese.
05 -
Brush the edges of the dough with the beaten egg, roll it tightly like a jelly roll, and pinch the seams to ensure it's sealed.
06 -
Combine the remaining melted butter with garlic powder, Parmesan cheese, and parsley. Brush this mixture generously over the top of the stromboli. Use a sharp knife to score diagonal cuts into the dough without cutting all the way through.

Place the stromboli on a baking sheet and bake in the preheated oven for 25-30 minutes, until the crust is golden brown.

Let it cool for approximately 5 minutes after baking, then slice into portions. Serve warm with marinara sauce on the side.
