Caldo Verde is a traditional Portuguese soup made with kale, potatoes, onions, garlic, and Portuguese chouriço (smoked sausage). The soup is cooked until the potatoes are tender and then pureed to create a creamy texture. The kale is thinly sliced and added to the soup, giving it a vibrant green color. Caldo Verde is a comforting and nutritious soup that is often served with crusty bread. It is a popular dish, especially during the colder months.
