Which ingredient is likely NOT included in traditional Chicken Tortilla Soup?

In traditional Chicken Tortilla Soup, the primary ingredients typically include chicken, broth, vegetables, spices, and garnishes such as tortillas, avocado, and cheese. Tortillas are often cut into strips and added to the soup to provide a unique texture and flavor. Ancho sour cream and shredded cheddar jack cheese are common garnishes that enhance the dish's richness and creaminess, complementing the soup's flavors.

Croutons, however, are not a traditional component of Chicken Tortilla Soup. While they add crunch to various salads and soups, they do not fit the usual profile of ingredients in this specific soup. The lack of croutons aligns with classic recipes, which focus on tortillas as the key textural element, thus reinforcing why croutons are unlikely to be included in this dish.
