What is a common side served with many main dishes beside ribs?

The correct response is French Fries, as they are a versatile and popular side option that pairs well with a range of main dishes served at Chili's, including various grilled meats and burgers. French Fries are favored for their crispy texture and ability to complement the rich flavors of items like ribs, burgers, and chicken tenders, making them a staple in many casual dining settings.

Garlic Bread is typically associated with Italian dishes and is not as frequently paired with non-Italian items. Coleslaw, while a common side, is often specifically served with barbecued meats and is not as universally accompanying as fries. Rice Pilaf, although a viable side in other cuisines, is less commonly featured on the Chili's menu compared to French Fries. Thus, French Fries stand out as the most common and versatile side offered.
