From J.M. Hirsch's Venturesome Vegetarian Cooking. Thyme was replaced with fresh oregano; eggplant replaced with zucchini. You'll notice there's another interesting herb added to this recipe... Note: for dairy version, switch out ricotta cheese or cottage cheese for the tofu and add some shredded mozzarella, parmenan, asiago, etc.- (about 3/4 cup cheese).
