Favored by the Arabs, Za'atar Blend is a seasoning that is often mixed with olive oil to create a spread for pita and flatbread. It is also used to season vegetables and meat. The blend combines thyme, sesame seeds, and sumac, all of which bestow upon the seasoning its tart and fruity flavor. Other Za'atar blends also include oregano, marjoram, and savory. Try it in your pizzas or pitas.
