Adapted from Anne Willan, La Varenne.The original recipe calls for green beans; since I didn't have any, I substituted zucchini. Of course, as in most vegetable soup recipes, feel free to substitute whatever vegetables you have on hand, just adjust the cooking time accordingly. I decided to cook the potatoes along with the cauliflower instead of adding them later on as potatoes sometimes take longer to cook. For a dairy-free, vegan version, serve without the Parmesan cheese.
