Which dish is NOT typically considered a part of Olive Garden's iconic offerings?

The choice of sushi rolls is not typically considered a part of Olive Garden's iconic offerings because Olive Garden is primarily known for its Italian-American cuisine. The restaurant features a menu that highlights classic Italian dishes, such as Lasagna Classico, Eggplant Parmigiana, and Ravioli di Portobello, which are staples of their offering and reflect the brand’s focus on traditional Italian meals.

While other options represent well-known Italian dishes that are integral to Olive Garden's identity, sushi rolls do not align with the themes or cooking styles commonly associated with the restaurant. Therefore, the presence of sushi rolls would stand out as an outlier that doesn't fit the restaurant's established culinary framework.
