1 qt greek or regular yogurt
1 teaspoon salt
Stir salt into yogurt. Line a wire mesh strainer with either cheesecloth (at least two layers) or paper towels. Spoon yogurt into strainer; set over a bowl, cover loosely with saran wrap, and refrigerate overnight.
In the morning, bowl will contain much of the whey, which should be discarded. Greek yogurt will be ready if it has sat over night for about 8 hours. For regular yogurt, strain an additional 3-4 hours for maximum thickness.
Serve in a shallow bowl; drizzle olive oil, and top with a generous sprinkle of za’atar.
