A classic Italian dish where chicken is slow-cooked in a rich tomato sauce with bell peppers, onions, mushrooms, and aromatic herbs, resulting in tender, flavorful meat that's perfect over pasta or with crusty bread.
For a richer flavor, you can add a handful of pitted black olives or capers to the slow cooker along with the other ingredients. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
