Tahini, a smooth paste made from crushed sesame seeds and water, is an indispensable ingredient when it comes to Middle Eastern cuisine. It can be found in most organic or Asian grocery stores. Sesame seeds are rich in minerals like calcium, zinc, and manganese. They also make a great source of B vitamins and protein. Sesame seeds and paste are both frequently used in Middle Eastern dishes, like hummus, baba ganoush, skewers, sauces, bread, halva, cakes and granola bars. In this recipe, tahini is made into a sauce that tastes great on both salads and grilled vegetables.
