First start with the meatball sauce.
Heat the olive oil and sweat the onion for about 5 mins until soft.
Then add the garlic and chilli and fry for a minute.
Mix in the passatta, thyme, balsamic vinegar, salt, pepper and sugar and simmer for about 30 mins until done.
Make the meatballs
In a food processor mince together the onion, garlic, pepper, chilli and coriander till well chopped.
Add this mixture to the pork mince and also add in the parmesan, breadcrumbs, salt, black pepper and egg.
Combine everything together till well mixed.
Heat some oil in a frying pan and fry a very small amount of the meat mixture. Taste for seasoning and make any necessary adjustments.
Then divide the meat mix into 24 portions and shape each portion into a meat ball between the palm of your hands.
Then reheat oil in the frying pan and fry meat balls in batches making sure they are brown on each side and cooked through.
When done serve the meatballs topped with the sauce and some cheese.
