Preheat oven to 375°F

Lightly flour your workspace. Make a pizza dough rectangle measuring 12x14 inches. It is also possible to roll the dough onto parchment paper, so that you can directly bake the pizza in the oven.

Combine 1 Tbsp butter and minced garlic in a small bowl. Sprinkle the butter and garlic over the dough.

Sprinkle 1/2 cup mozzarella cheese over the dough. Leave a 1-1/2 inch border around the two long edges.

Add ham to the top of the cheese. Add 1/2 c. Mozzarella cheese to the top of the ham. Next, add the pepperoni and salami pieces. Sprinkle the remaining cheese over the pepperoni.

Use a fork to beat the egg in a small bowl. You can use a brush to cover the edges of the dough. (Where you left the cheese, think short, slow, long).

Next, roll the long edge of your jelly roll stromboli style. The long edge that does not have the egg wash should be your starting point. It should be rolled tightly to ensure it stays together. Use wet fingertips to seal the seam. Roll the stromboli until the seam is facing downward. To seal the dough, you may have to fold the sides under.

Transfer to a baking sheet or pizza pan.

Combine the remaining 2 Tbsp butter, garlic powder and parmesan cheese in a small bowl. Add chopped parsley to the bowl. Butter mixture should be applied to the top of the stromboli. Use a sharp, serrated knife to make small diagonal cuts along the top of the stromboli at every 2 inches.

Bake in a preheated oven for 25-30 mins or until the top turns golden brown.

Let cool in the oven for 5 minutes. Use a serrated knife to cut 8 slices.

Serve with warm marinara sauce
