What type of sandwich is offered as a menu option for lunch alongside burgers?

The choice of a chicken sandwich is correct as it aligns with the popular fast-food offerings that often accompany burgers on lunch menus. Chicken sandwiches are a staple in many fast-food chains and are typically featured prominently alongside burger options to cater to a diverse range of customer preferences.

Including chicken sandwiches allows establishments like Jack in the Box to appeal to those who might prefer poultry over beef, contribute to a broader menu variety, and target health-conscious consumers who may view chicken as a lighter alternative. Consequently, the presence of a chicken sandwich on the lunch menu helps meet varied dietary choices and enhances the overall appeal of the menu.

Other types of sandwiches, such as those made with beef, turkey, or vegetarian fillings, can also be found at various eateries, but the chicken sandwich stands out as a frequent and popular choice that fits the context of fast-food lunch offerings.
