1. Squeeze the filling from the sausages and roll them separately in your hands to make small meatballs. Heat a very large frying pan over medium heat, add half the oil and fry the onion for about 6 minutes, until golden. Add the garlic and the meatballs and fry until the meatballs are browned. Add the tomato paste and red wine and bring to a simmer, then add the passata and cover the pan. Simmer for about 20 minutes. 

2. Bring a large pot of water to a boil and add salt. Cook the spaghetti according to the packet directions, checking the pasta two minutes before the end of the cooking time. When the pasta is al dente, use tongs to transfer the pasta from the water directly to the sauce. Add the remaining olive oil and toss to coat the pasta. Serve with parmesan cheese and a good grind of black pepper.
