In a medium mixing bowl, melt the mozzarella in the microwave for about 30 seconds.
Stir in the remaining dough ingredients into the mozzarella.
Roll into a ball and knead 1 or 2 times. Place the dough between 2 sheets of parchment paper.
Roll the dough out to a 10.5" circle about ½" thick using a rolling pin.
Layer the remaining ingredients into a 10.5" skillet in this order: ham, salami, pepperoni, capicola, 1⁄2 the provolone, bell pepper, tomato, olives, red onion, and banana peppers.
Drizzle the olive oil, red wine vinegar, and Italian seasoning over the top, then top with the remaining cheese and the crust.
Transfer to the oven and bake for 25-30 minutes until the crust is browned. Serve immediately.
