Prepare the pasta according to package directions, and drain.
Soak in cold water for 3 minutes, to completely chill the pasta.
Prepare the dressing while the pasta cooks.
Mix the sour cream, mayo, lemon juice, garlic, mustard, Worcestershire, hot sauce, and salt and pepper until blended. (for extra cheesy dressing add 1 oz grated Romano or Parmesan Cheese.
Blot the pasta dry with a paper towel so the dressing will coat that pasta and not "slip" off. Add 1/2 the dressing to the pasta and stir well.
In a medium bowl, add 1/2 the dressing to the pasta and stir well. Add more dressing as needed as desired.
If serving immediately mix a couple of tablespoons dressing with the chicken and stir that into the pasta, stir in the chopped lettuce, top with grated cheese and croutons, salt and pepper, and serve.
I usually prepare the pasta the day ahead when making pasta salad and allow the dressing time to absorb a bit, then add additional dressing before serving.
In this recipe do not mix the lettuce with the dressing until closer to serving. Add additional dressing if desired.
When meal prepping place the dressed pasta in the bottom of the dish, add the lettuce and cheese on top. Place the chicken on top. Then place the croutons in a bag, and tuck it inside the container so they stay crunchy.
Top with salt and pepper and serve.
