Caldo Verde is a traditional Portuguese soup made with potatoes, kale, onions, garlic, and Portuguese chouriço (smoked sausage). The potatoes are cooked until tender and then mashed to create a creamy base for the soup. The kale is thinly sliced and added to the pot, along with the chouriço, which adds a smoky and savory flavor. Caldo Verde is a comforting and nourishing soup that is often served with crusty bread.
