I love real Italian cooking and don’t do nearly enough of it. Many traditional Italian recipes not only taste good but have the benefit of being vegetarian or nearly so, and not too fattening.
I expect there are as many versions of the Tuscan soup ribollita (reheated soup) as there are cooks. This is based on Ursula Ferrigno’s recipe in Bringing Italy Home, and I like it because it’s vegetarian. If you are a confirmed carnivore, you could easily add a ham hock or some bacon. As the name suggests, it’s best reheated the day after you make it.
Vegetables can be varied according to taste and availability. I’m sure in Tuscany it always has cavolo nero in it, but you can’t get that here, so I always use dark green Savoy cabbage.
Oil: you must use the best you can get for drizzling over the top; you can get away with slightly less good for the cooking, but it should be extra-virgin.
