Some of Italy's finest ingredients make up this warming soup. Adapted from 'Pasta Cooking' by Parragon.... the original recipe called for spinach, which I didn't fancy, so I subbed zucchini. I get the impression that our zucchini are generally a bit smaller than those in the Northern hemisphere, so balance the amount used with your other vegetables, just feel your way! You don't want your soup to be over-loaded with any one vegetable. Hope you enjoy!
