Ribollita is a dish that derives from the typical soup of stale bread and vegetables that is traditionally prepared in some areas of Tuscany, in particular in the Piana di Pisa, in the area of Florence and Arezzo. It is a typical "poor" dish of peasant origin, whose name derives from the fact that once the peasants cooked a lot of it (especially on Fridays, being a low-fat dish) and then "reboiled" in the pan in the following days, from here which takes the name of ribollita, because the real soup is heated twice, otherwise it would be a trivial soup of bread and vegetables (not to be confused with the soup of bread)
