Prepare the Potatoes 🥔: Bring a pot of salted water to a boil. Add the potato chunks and parboil for 5-7 minutes until just tender but still firm. Drain and toss with olive oil, salt, and rosemary (or Italian herb blend, if using). Spread them out on a lined baking tray.
Prepare the Meatballs 🍖🧀: Preheat the oven to 200°C (400°F). In a bowl, mix the pork, veal, and beef mince with the finely chopped onion, Italian herb blend, salt, and black pepper. Divide the mixture in half. Flatten each portion into a patty, place a mozzarella cube in the centre, then wrap the meat around it, sealing well to form two large meatballs.
Roast 🍖🔥🥔: Place both the meatballs and potatoes in the oven. Roast for 20-25 minutes until the meatballs are golden brown and cooked through. The potatoes will also take 20-25 minutes but can be left for longer for extra crispiness. Flip them halfway through for even browning.
Make the Pomodoro Sauce 🍅: While everything is roasting, heat 1 tablespoon olive oil in a saucepan over medium heat. Add the chopped tomatoes, salt, and black pepper. Simmer for 15-20 minutes, stirring occasionally, until thickened.
Serve 🍽️: Plate the mozzarella-stuffed meatballs with the crispy roasted potatoes and spoon the Pomodoro sauce on the side.
Eat up and enjoy! 🍖🧀🥔🍅🇮🇹
