Grease your hands with a bit of oil and, with oiled hands, form the yogurt into balls. You can roll the balls in zaatar or leave them plain. At the bottom of a jar, place slices from 2 garlic cloves, a few slices of chili, and sun-dried tomatoes. Pour a bit of olive oil, then arrange a layer of balls on top. Finish by pouring more olive oil and store in the refrigerator.
