Tortilla is a type of thin, unleavened flatbread that predates the arrival of Europeans to the Americas. This bread is made from powdered corn or wheat flour, and is considered a basis of many traditional Mexican dishes, such as tacos, tostadas, enchiladas, flautas, quesadillas, chilaquiles, and tortilla soup. Warmed corn tortillas are also often served as an accompaniment to stews, soups, grilled meats and other dishes, as bread might be served in other cuisines. Nutritionally, Tortillas are a great source of fiber, which helps to improve gastrointestinal functions.
