1. Preheat the oven to 375 degrees.
  2. Press one of the pizza crusts into the bottom and up the sides of a cast iron skillet.
  3. Place the olives, peppers, and italian dressing in a ziploc bag and shake to combine.
  4. In this order, layer the ingredients inside the crust: ham, half the cheese, hard salami, the remaining cheese, followed by the olive mixture.
  5. Place the second crust over the top and pinch along the edges to seal. Using a sharp knife, cut 4 slits in the top to allow the steam to escape. Using a pastry brush, brush a thin layer of beaten egg over the top of the crust.
  6. Bake at 375 degrees for 35-40 minutes or until golden brown and cooked through. Let set 5 minutes for before slicing and serving.
