Dry the jarred roasted red bell peppers and measure half a cup of pepperoncini rings, then mix them with black pepper in a bowl.
Open the crescent roll dough and lay out the triangles in a circular arrangement on a pizza stone or pan, ensuring the wide ends overlap in the center.
Place the halved Provolone cheese around the outer edge, followed by the ham, spicy pepperoni, pepper mixture, and top it off with mozzarella cheese.
Fold the pointed ends of the crescent triangles over the filling and tuck them under to secure it all, then brush with the beaten egg and add some black pepper on top.
Bake for 18-22 minutes in the preheated oven until the top is golden brown and the bottom is thoroughly cooked.
