Which of the following toppings is included in the loaded baked potato soup?

The loaded baked potato soup features mixed cheese as one of its key toppings. This addition enhances the creamy, rich flavor of the soup, providing a combination of textures and tastes that align with the hearty nature of a baked potato. The mixed cheese typically includes varieties such as cheddar and Monterey Jack, which melt beautifully and complement the other ingredients like bacon, green onions, and sour cream. This combination creates a comforting dish that embodies the essence of a loaded baked potato, making it a popular choice among customers.

The other options do not align with the traditional offerings typically found in this soup, as shredded lettuce, olive tapenade, and cilantro are not standard ingredients that would enhance or fit within the flavor profile of loaded baked potato soup.
