Sopa Azteca, also known as Tortilla Soup, is a traditional Mexican soup made of fried corn tortilla pieces, submerged into a broth of tomato, garlic, and onion. It is garnished with avocado, cheese, and chili peppers and served with sour cream. It’s a flavorful, hearty dish that can be found throughout Mexico, though it’s particularly associated with central and southern regions of the country.
