Bring a large pot of salted water to a boil. Cook the pasta according to the package directions until al dente. Drain and rinse under cold water to stop the cooking process and cool the pasta.
Prep the ingredients: While the pasta cooks, chop the romaine lettuce, cube the cooked chicken, cook and crumble the bacon, and shred the parmesan if needed.
Mix the salad: In a large mixing bowl, combine the cooled pasta, chicken, chopped bacon, chopped romaine, parmesan cheese, and Caesar dressing. Season with salt and black pepper to taste. Toss everything together until well coated.
Right before serving, fold in the croutons so they stay crispy.
Serve immediately, or chill for 30 minutes if you prefer it cold. This pasta salad is filling enough for a light dinner or perfect as a hearty side dish.
