What can you order as an extra item apart from sauces at Jack in the Box?

Sliced jalapenos are a customizable option available at Jack in the Box, allowing customers to add extra spice to their meals or enhance the flavor of their burgers, tacos, and other items. This choice fits well within the context of extra items that can be added to an order, alongside the sauces.

While French fries, bacon strips, and onion rings are popular menu items, they typically form part of their own categories, such as sides or add-ons for specific meals, rather than being considered extras that can be specifically added to enhance another item. This distinction makes sliced jalapenos the most fitting answer for what can be ordered specifically as an extra item apart from sauces.
