Roll out your pizza dough into a large rectangle on a floured surface. Brush it lightly with olive oil to prevent sticking and add extra flavor. Sprinkle oregano and a pinch of red pepper flakes over the dough for a flavorful base.
Chop green and black olives finely and add them to a mixing bowl. Toss in capers, minced garlic, olive oil, and a dash of oregano. Mix everything together to create a zesty olive salad.
Lay thin slices of Genoa salami, mortadella, and ham evenly across the dough. Follow that with layers of provolone and mozzarella for that gooey, cheesy goodness. Spread your olive salad generously over the meats and cheeses.
Starting from one long edge, carefully roll the dough into a tight log. Be gentle to avoid tearing the dough. Pinch the seam to seal the roll, so none of the fillings escape during baking.
Place the roll seam-side down on a lined baking sheet. Brush the surface with an egg wash to give it that golden, glossy finish. Bake at 375°F (190°C) for 20-25 minutes, or until the roll is beautifully golden and crisp.
Once baked, allow the roll to cool slightly before slicing into 1-inch pieces. Serve warm and enjoy every bite!
