Instructions:
Preheat oven: Set your oven to 375°F (190°C).
Prepare dough: Unroll pizza dough on a floured surface. Flatten and stretch if necessary.
Add garlic butter: Brush a layer of garlic butter over the dough.
Layer fillings: Start with pepper jack cheese, followed by pepperoni, salami, ham, and mozzarella.
Season: Sprinkle garlic powder and Italian seasoning over the fillings.
Roll dough: Roll the dough from one side to the other, tucking in the ends and pinching the seams.
Prepare for baking: Transfer the Stromboli to a baking sheet lined with parchment paper or greased with cooking spray. Brush with an egg wash and cut several slits on top.
Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until golden brown and cheese is melted and bubbly.
Cool and serve: Let the Stromboli cool for a few minutes before slicing. Serve with marinara sauce or your favorite dipping sauce.
