Lebanese Za'atar (or Zatter) is a blended seasoning, sprinkle on bread dough before baking, rub on chicken or fish before grilling or toss with saute vegetables or boiled potatoes.
Za'atar is traditionally dried in the sun and mixed with salt, sesame seeds and sumac. It is commonly eaten with pita, which is dipped in olive oil and then za'atar.
Za'atar is used as a seasoning for meats and vegetables or sprinkled onto hummus. It is also eaten with labneh (yogurt drained to make a tangy, creamy cheese), and bread and olive oil for breakfast, most commonly in Jordan, Israel, Syria, and Lebanon, as well as other places in the Arab world.
