Heat the olive oil in a Dutch oven or other heavy pot over medium-high heat. Add the sausage and pancetta and cook until well browned. Add the ground pork, thyme, fennel, garlic, chili peppers, onion, oregano, and roasted red pepper, and cook until soft, about 5 minutes. Stir in the tomato paste and cook for 1 minute. Deglaze the pan with the wine, stirring and scraping up any brown bits from the bottom of the pan. Add 2-3 cups chicken stock and simmer for a few minutes.
