Ribollita is a traditional Tuscan vegetable and bread soup. It is made with a variety of vegetables such as kale, cabbage, carrots, celery, and onions. The vegetables are cooked in a flavorful broth and then mixed with stale bread. The soup is then left to simmer until the bread absorbs all the flavors and becomes soft and creamy. Ribollita is a delicious and nutritious dish that is often enjoyed during the colder months in Tuscany.
