Set your oven to 350°F and spray a 9x13-inch dish to keep things from sticking.

Take one dough sheet and press it into the dish, covering the bottom and partway up the sides. Arrange half the provolone cheese on top of it.

Stack the pepperoni, ham, salami, roasted red pepper slices, pepperoncini, and then top with the rest of the provolone.

Lay the second crescent dough sheet on top, pinching the edges all around to seal it. Whisk together the egg, pesto, and parmesan cheese in a bowl, then brush it all across the surface.

Cover the dish loosely with greased foil and bake for 30 minutes. Take the foil off and let it bake another 15-20 minutes until it turns golden. Let it sit for 10 minutes before slicing.
