What is another option for a side item apart from fries?

Onion rings are indeed a popular alternative to fries on many fast-food menus, including Jack in the Box. They provide a crunchy texture and a different flavor profile, appealing to customers looking for variety in their side items. Onion rings can enhance a meal by offering a savory option that complements burgers and sandwiches, making them a widely recognized and favored choice among side items. Other options like salad, soft drinks, and breadsticks, while relevant, don't typically fall under the category of traditional side items served alongside entrees in the same way that onion rings do.
