Roll out one loaf of bread dough to a rectangle that is 1/4 inch thick.
Spread pizza sauce on the entire rectangle, leaving a 1 inch border all the way around.
Place half of the salami in single layer, covering the pizza sauce.
Repeat with half of the American cheese, ham, pepperoni and mozzarella cheese.
Bring the long sides together over the center, and pinch together to seal.
Turn over, so that the seam is on the bottom, and place on an ungreased baking sheet.
Repeat all of the steps above with second loaf of bread dough.
Brush the top of each stromboli with olive oil and sprinkle Italian seasoning over the top.
With a sharp knife, cut 3 diagonal slices in each stromboli to allow the steam to escape.
Bake at 350 degrees for 15-20 minutes, or until golden brown.
Allow to cool slightly before slicing.
Notes
Extra Sauce: Serve extra marinara sauce on the side in a small bowl for dipping.
Fresh Herbs: Top with fresh parsley and basil to give your stromboli a kick of flavor. You can also add pizza seasoning or red pepper flakes to the stromboli before baking.
Vegetables: Make a meatless stromboli and fill with your favorite vegetables such as spinach, mushrooms, and broccoli.
Hot Chicken Stromboli: Make a hot wing stromboli with chicken, cheese, and hot wing sauce.
Air Fryer: You can also make stromboli in the air fryer, although you will have to adjust the size accordingly.
