Which option is only served on the lunch combo menu?

The double burger is specifically designed to be part of Chili's lunch combo offerings. This menu is aimed at providing customers with a range of lighter, quicker options that are perfect for lunch. The double burger, with its combination of flavors and ingredients, fits the criteria for a satisfying yet manageable lunch meal.

In contrast, the chicken fajitas, boneless wings, and steak and shrimp are available beyond just the lunch combo menu, making them suitable for both lunch and dinner. This distinction helps customers identify the options tailored specifically for a fast and fulfilling lunch experience. Recognizing which items are exclusive to the lunch combo menu is an essential aspect of understanding Chili's offerings and catering to customer preferences during peak lunch hours.
