Prepare the Dough : Preheat your oven to 375°F (190°C). Unroll the pizza dough on a lightly floured surface, shaping it into a rectangle.

Layer the Fillings : Evenly layer the deli ham, Genoa salami, and pepperoni across the dough, leaving about 1-inch of space on the edges. Top with provolone or mozzarella cheese.

Roll It Up : Starting from the shorter side, carefully roll the dough into a tight log. Pinch the edges and seam to seal the filling inside.

Make the Garlic Butter Topping : In a small saucepan, melt the butter over low heat. Stir in the minced garlic and cook for 1 minute until fragrant. Remove from heat and add the chopped parsley.

Brush and Top : Place the stromboli seam-side down on a parchment-lined baking sheet. Brush the garlic butter mixture generously over the top and sprinkle with grated Parmesan cheese.

Bake to Perfection : Bake in the preheated oven for 18-20 minutes or until golden brown and crispy. Allow the stromboli to cool slightly before slicing into thick pieces.

Serve and Enjoy : Serve warm with a side of marinara sauce for dipping, if desired.
