Low fat, healthy soup that's very filling. When my girlfriends come for a meal, I make this soup to avoid a riot, seriously. Garnish with Parmesan, Romano, or put out a block of parmagiana reggiano cheese and a microplane and let guests garnish their bowls of soup as they wish. Serve with some good warm bread. Note: If you cannot find pancetta (basically Italian bacon) you can substitute prosciutto ham which is also not smoked. I've heard you can use bacon if you blanch it first to remove the smoky flavor, but I think I'd just leave it out altogether. This is an easy soup to make and that just seems like work!
