What is the primary meat in the sirloin and chicken critter combo?

The sirloin and chicken critter combo primarily features chicken tenders as the second protein alongside the sirloin steak. Chicken tenders are a popular choice in many dishes for their tenderness and flavor, making them an ideal accompaniment to the sirloin. This combination provides a balanced meal with both beef and chicken, catering to those who enjoy a variety of flavors and textures in their dining experience.

The other options do not apply in this context. Chicken breast would typically refer to a specific type of preparation or cut rather than the tenders used in this dish. Ground beef is not featured in this combo, as the primary beef component is the sirloin steak. Pork, while a popular protein choice, is not included in the sirloin and chicken critter combo, which focuses on sirloin and chicken tenders.
