Olive Oil Zucchini Bread

This moist loaf, made with olive oil and yogurt, is less sweet and more complexly flavored than most zucchini breads. Grated lemon zest gives a gentle brightness, while brown sugar adds a caramel sweetness, and cinnamon makes it spicy and rich. Serve slices plain or buttered, or spread thickly with cream cheese for a more tangy and luscious variation.
