Begin by bringing a large pot of salted water to a rolling boil. Add the rotini pasta and cook according to the package directions, typically about 8 to 10 minutes, until al dente. Drain the pasta, and then rinse it under cold water to stop the cooking process.

In a large mixing bowl, combine the cooled pasta, diced cooked chicken, and chopped Romaine lettuce. If adding cherry tomatoes, slice them in half and toss them in as well. Gently fold the ingredients together until evenly distributed.

Drizzle your favorite Caesar dressing over the salad mixture. Toss gently to ensure every piece of pasta and chicken is coated.

Sprinkle grated Parmesan cheese over the top and fold into the salad, ensuring it's well-integrated throughout.

Taste your salad and add salt and freshly cracked pepper as desired. Toss the salad again to evenly distribute the seasoning.

Just before serving, sprinkle croutons on top for crunch. Chill in the fridge for up to 2 hours before serving.
