2) Add the spare ribs to the pancetta fat and brown well on both sides. Remove the ribs to a baking sheet and bake in the oven until tender, about 1 1/2 hours.
3) Meanwhile, add the sausage to the braising pan and brown both sides. Add the peppers, onion and garlic and cook until translucent, then deglaze the pan with wine. Simmer for a couple of minutes, then add the tomatoes.
4) Bring back to a simmer and add the cooked pork ribs, parsley, basil, chili flakes and salt and pepper, to taste. Simmer on low to medium heat, covered, for another 1 1/2 hours.
5) Serve over the cooked pasta, and garnish with pancetta, spring onions and Parmesan.
