Lebanese spinach fatayers are savory pastries filled with a mixture of spinach, onions, and spices. Recipe developer Annabelle Randles also adds feta cheese for a tangy flavor. The dough is made with flour, sugar, yeast, salt, water, and olive oil. The fatayers are shaped into triangles and baked until golden. They can be enjoyed warm or at room temperature and are great with yogurt-based dipping sauces or as part of a mezze spread. They can also be frozen and reheated later. Sumac, a spice with a tart, lemony flavor, is a common ingredient in Middle Eastern cuisine and can be added for extra flavor.
