Za'atar is a traditional Middle Eastern aromatic spice mixture of za'atar herb, sumac and white sesame seeds. With an earthy, woodsy flavour, za'atar is a popular tabletop condiment that is often used in bread making. For a tasty treat, brush pita bread with olive oil and sprinkle it with za'atar. Cut the bread into wedges and bake in a 350° oven for 5-10 minutes, just until the bread is browned and crisp. Za'atar also makes a wonderful seasoning for roasted chicken or lamb stew.
