This vegetable soup with kale, Ribollita, is one of a number of thick soups from Italy served with a slice of bread in the bottom of the bowl. It has no additional pasta or rice. The name Ribollita means reboiled. Traditionally the soup was made by heating leftover vegetable soup in an earthenware pot in the oven. This recipe was inspired by the comprehensive Italian cookbook, The Silver Spoon, Phaidon Press, 2005. As with most plant-based recipes, the method of cooking the vegetables is crucial to obtaining the deepest, richest flavor for the dish. In this recipe, some of the vegetables are sautéed in wine before they go into the stock. These caramelized vegetables provide a contrast with the sharper kale and tomatoes in the stock.
