Toast the pizza bread

• Preheat the oven to 200 °C.
• Place the halved pizza bread on a baking tray and toast until lightly crisp.

Cook the steak

• Heat the olive oil in a frying pan over high heat.
• Season the steak with salt and pepper and sear to the desired doneness.
• Let it rest, then slice.

Assemble the burger

• Spread pesto alla Genovese on the pizza bread halves.
• Layer the tomato slices, the sliced steak and the mozzarella di Bufala.
• Close the burger and top with arugula.

Melt and serve

• Return the burger to the oven briefly so the mozzarella softens.
• Serve immediately.
