Ribollita is a classic Tuscan vegetable and bread soup. It is made with a variety of vegetables such as kale, cabbage, carrots, and beans, along with stale bread. The vegetables are cooked down until tender, then the bread is added to thicken the soup. Ribollita is typically served hot and is a hearty and nutritious dish. It is often enjoyed during the colder months and is a great way to use up leftover vegetables.
