What is considered a side choice for salads?

The correct answer identifies the "Guest Choice" as a side choice for salads, which emphasizes the customizable nature of salads at Chili's. This option allows guests to personalize their dining experience by selecting sides that complement their salad, highlighting the flexibility and variety offered on the menu.

Considering the other options, while croutons can be a common salad topping, they are typically not categorized as a side dish in the same way that "Guest Choice" is meant to represent a selection that the diner can tailor to their preferences. French fries and onion rings, although delicious side items, are generally considered standard sides rather than salad-specific options. The concept of "Guest Choice" reflects the restaurant's approach to providing an adaptable menu, catering to individual tastes and ensuring a satisfying dining experience.
