Which of the following is NOT a protein option on the smokehouse combo?

The smokehouse combo is a specific menu item at Chili's that highlights a variety of smoky, protein-packed selections. Among the options listed, smoked brisket, brisket quesadilla, and cheesy bacon BBQ chicken all feature as part of the combo, focusing on robust, smoky flavors that are central to that dish.

Grilled chicken, while a popular item on the overall menu, does not align with the smokehouse theme of the combo because it typically does not incorporate the same smoky, grilled preparation that sets the other items apart. Therefore, identifying grilled chicken as not being part of the smokehouse combo is accurate and reflects the specific offerings associated with that selection.

By understanding the focus on smoked meats and BBQ flavors within the context of the smokehouse combo, it becomes clear why the grilled chicken is not included as a protein option in this case.
