With red beans and quinoa, this vegetarian version of tortilla soup is just as flavorful, hearty, and protein-packed as its traditional chicken counterpart. Red beans are the hearty powerhouses in this vegetarian soup. Chef Toni Sakaguchi at The Culinary Institute of America garnishes the soup with chips, avocados, cilantro, and lime wedges. You will love the bold smoky flavors of this protein-packed soup!
