You can serve small quantities of this Tuscan bean dish on crostini, as an appetizer, or larger quantities as a hearty soup.
To cook the beans, soak overnight in plenty of cold water. Discard this water and cook on a low heat for approximately an hour and a half, until tender.
Cooking with pieces of kombu seaweed improves the digestibility of legumes/pulses.
