Lightly dust countertop with flour. Roll dough into a 10”x12” rectangle.
With a long side of the dough facing you, spread the pizza sauce (if using) evenly across pieces of dough, leaving 1” border on both of the longer sides. Next, spread 1 cup of mozzarella evenly across dough. Sprinkle Italian seasonings on top of cheese.
Overlapping slightly, layer the ham, salami, pepperoni and provolone lengthwise down the dough. Sprinkle Parmesan cheese evenly on top.
Starting with a long edge, roll the dough into a tight cylinder; pinch edges of dough to seal. Using a sharp knife, slice the dough into 12 equal pieces. Place one piece in each of the prepared muffin cups.
Bake for 15 minutes. Remove pan from oven and sprinkle remaining ½ cup of mozzarella cheese on top of stromboli. Continue baking for 13-15 more minutes, or until Stromboli are golden brown.
Let cool for 5 minutes before removing from pan and serving. (Tip: The meats and cheeses will release a lot of oil, so just gently blot the tops of the Stromboli while they’re hot to soak up the excess oil.)
