Caldo Verde is a traditional Portuguese soup made with kale, potatoes, onions, garlic, and Portuguese chouriço (smoked sausage). The soup is made by simmering the kale and potatoes until tender, then blending them together to create a creamy base. Sautéed onions and garlic are added for flavor, and thin slices of chouriço are added as a garnish. Caldo Verde is a comforting and nourishing soup that is often enjoyed during the colder months in Portugal.
