Lunch, often lasting over an hour, is served between noon and 2 o'clock, typically around 1 o'clock and dinner is generally served around 8 o'clock. There are three main courses, with lunch and dinner usually including a soup. A common Portuguese soup is "caldo verde", which consists of a base of cooked, then pureed, potato, onion and garlic, to which shredded collard greens are then added. Slices of "chouriço" (a smoked or spicy Portuguese sausage) are often added as well, but may be omitted, thereby making the soup fully vegan.
