Which component is part of the grilled chicken Caesar?

The grilled chicken Caesar salad is a classic dish that emphasizes the combination of grilled chicken, romaine lettuce, Caesar dressing, croutons, and often Parmesan cheese. Strips of grilled chicken are a fundamental component of this salad, providing protein and enhancing the overall flavor profile. The grilled chicken is typically seasoned and cooked to perfection, making it a centerpiece of the dish and contributing to the salad's heartiness.

Other options do not align with the traditional ingredients found in a grilled chicken Caesar salad. Italian dressing is not standard in this dish, as it typically uses Caesar dressing instead. Shredded mozzarella is not a common ingredient in classic Caesar salads, which traditionally use Parmesan. Chopped celery is also not a typical component, as it is not a standard ingredient in a Caesar salad. Therefore, strips of grilled chicken are essential to the identity of the salad, making this choice the correct answer.
