Preheat your oven to 375°F (190°C).
Roll out the pizza dough into a large rectangle on a floured surface.
Layer the ham, salami, and provolone cheese evenly over the dough, leaving a 1-inch border.
Spread the marinara sauce over the toppings, then sprinkle with Italian seasoning.
Roll the dough tightly into a log, pinching the seams to seal.
Brush the log with beaten egg and place it on a baking sheet lined with parchment paper.
Bake for 25-30 minutes or until golden brown.
Let the Stromboli cool slightly before slicing and serving.
