Cook the pasta according to package instructions. Drain and rinse under cold water to cool.

In a large mixing bowl, combine the cooked pasta, diced chicken, chopped romaine lettuce, halved cherry tomatoes, and grated Parmesan cheese.

In a small bowl, whisk together the Caesar dressing, lemon juice, and garlic powder until well combined.

Pour the dressing over the salad mixture and toss gently to combine. Adjust seasoning if necessary.

Transfer the salad to a serving bowl and top with croutons and chopped parsley. Serve immediately.
