I know, I know. Too good to be true.
500g (1.1lbs) lean minced beef 50g (1/2 cup) panko or fresh breadcrumbs 4 tbsp grated parmesan 1 small onion, finely chopped 1 tsp dried oregano 1 egg 2 tbsp olive oil
pinch of salt and pepper 1 x 200g (7oz) pack mozzarella, chopped into 24 chunks (2 extra, just in case)
Mix all of the meatball ingredients except the mozzarella in a bowl with your hands. Squash it all together but don’t overmix as this will make the meatballs tough. Take a golf-ball chunk of the mix in your hands and flatten it into a pattie.
