Serves 6 as an appetizer
Yogurt cheese begins with plain yogurt, which is poured into a strainer lined with cheesecloth and refrigerated for a few hours or overnight. The yogurt releases some whey and turns into a tangy white spread. It forms the basis of this appetizer, which can also begin with unflavored Greek yogurt. Spoon it onto a dish, and beside it, set ripe avocado mashed with lemon juice, a rich element to balance the yogurt's sharpness. Then spoon a little salad of finely chopped tomato, bell pepper, black and green olives, and capers to offer fresh and slightly salty tastes. You need pita crisps, sweet potato chips, or hearty wheat crackers to swoosh through the smooth green and white mounds. Serve it as an hors d'oeuvre with drinks or on individual plates as a first course.
