Ribollita is a traditional Tuscan soup that is made with leftover bread and vegetables. It is a thick and hearty soup that is perfect for a winter meal. The soup is typically made with cannellini beans, kale, cabbage, carrots, and onions. The bread is added to the soup and then simmered until it becomes soft and mushy. Ribollita is a delicious and satisfying dish that is often served with a drizzle of olive oil and a sprinkle of Parmesan cheese.
