You will get more fiber from this pasta by choosing orzo made from whole grain flour instead of white flour. While white orzo is a low-fiber food, it is fortified with thiamin, niacin, B6, folate, iron, and zinc. Plus, when paired with high-fiber foods, such as black beans, kale, and avocado as in this Black Bean Salad with Corn and Avocado, orzo can be a part of a healthful diet.
