Method
1. Pre-heat oven - 200°C
2. Line a clean baking sheet with foil then set aside
3. Add olive oil, ground pork, ground beef, zucchini, button mushroom, parmesan cheese, onion, fresh parsley, worcestershire sauce, ground cumin, egg, egg yolk, salt and black pepper to a clean large mixing bowl
4. Squash it all together but don’t overmix as this will make the meatballs tough
5. Shape the meatballs into little balls – the size of a golf ball – and place them on a baking tray
6. Put in the oven for about 20-25 mins
7. Whilst the meatballs are cooking, make the sauce: fry the onions in the olive oil on a low heat for about 5 mins
8. Add the garlic, and red pepper and cook for another couple of mins
9. Add canned tomatoes, tomato purée, dried oregano, sugar, salt and black pepper to the Dutch oven
10. Simmer - approx 10 min
11. Then take the cooked meatballs out of the oven and add them to the tomato sauce (leave the oven on)
12. Sprinkle the mozzarella and cheddar on top
13. Place back in the oven for 15-20 mins until the cheese is melted and golden
14. Serve
