This easy soup recipe is inspired by cocido, the hearty stew of assorted meats, chickpeas and vegetables considered a national dish of Spain. Each region, family and restaurant has its own variation, but this slow-cooker soup has enough meat to satisfy the carnivores and enough vegetables to make it healthy. Ask for a 4-ounce slab of Serrano ham or prosciutto at your deli counter instead of buying slices. If you don't have a 6-quart (or larger) slow cooker, opt for the stovetop variation instead.
