I start by preheating my oven to 500°F (260°C) with the rack in the lower third. While it heats, I lightly flour my counter and cut the dough in half. This makes it easier to handle and shape later.
Next, I stretch each half into a circle. I place mozzarella on one half of each circle, leaving a small border. Folding it over creates a half-moon shape, and I brush the top with olive oil for a golden crust.
I heat a cast iron skillet with a little olive oil. Each folded dough goes on the pan for 2–3 minutes until the bottom crisps. This step ensures a perfect texture without sogginess.
Once the bottom is golden, I transfer the sandwiches to a baking sheet. Baking in the oven for 10–12 minutes finishes cooking the dough while keeping it soft inside.
After a quick 2-minute rest, I carefully unfold the sandwiches. I spread pesto on both inner sides, layer prosciutto, add burrata, and tuck in tomato slices. A sprinkle of Parmesan, a drizzle of olive oil, and seasoning complete the sandwich.
