Walnuts, feta, and lemon in the filling, and sweet, juicy currants in the tomato sauce, fragrant with sherry and cinnamon. All this adds up to an anything but bland zucchini dish, true to its Greek lineage. Straight from the Moosewood Restaraunt New Classic cookbook! Serve this with a crisp cucumber salad and some Provencal Olives, Braised Olives in Tomato Sauce, or Kalamata Olives with Roasted Garlic for a meal that is complete! Enjoy!
