Preheat your oven according to the instructions on the Pillsbury pizza crust package.

Unroll the pizza crust onto a clean surface and stretch it gently to fit the size of your baking sheet.

Layer the deli meats evenly across the stretched pizza crust, starting with the ham, followed by salami and pepperoni.

Add the provolone cheese or mozzarella on top of the meats.

Roll the Stromboli lengthwise, keeping the fillings tucked inside, and pinch the seam tightly to seal.

Score the top of the Stromboli a few times with a serrated knife to allow steam to escape.

Melt the butter and mix in the minced garlic and chopped parsley. Spread this mixture evenly over the top of the Stromboli.

Place the Stromboli on a lined baking sheet and bake according to the pizza dough package instructions, until golden brown.

Let the Stromboli cool for a few minutes before slicing and serving.
