Which of the following is not a side item for sandwiches and burgers?

Sandwiches and burgers are typically accompanied by side items that complement their flavors and textures, enhancing the overall dining experience. The correct answer identifies spinach salad as the item not commonly served as a side for sandwiches and burgers.

While French fries and cole slaw are classic accompaniments that often appear on menus alongside these main dishes due to their popular pairing and ability to absorb flavors, dirty rice is also a hearty side that can accompany sandwiches, especially in more regional or themed dining settings. Spinach salad, on the other hand, is generally regarded as a separate, lighter dish and is less likely to be requested or served as a side to sandwiches or burgers. It fits more into the category of a starter or a standalone salad rather than a classic side item in this context.
