Add the dressing ingredients (except for the Parmesan cheese, salt, and pepper) to the bowl of a food processor. Blend until smooth. Add the Parmesan and pulse 1-2 times. Add the salt and pepper to taste.
Salad
Bring a large pot of salted water to a boil (salt the water with 2 teaspoons of salt). Add the pasta and cook according to package directions. Drain and rinse.
In a large mixing bowl, combine the romaine, chicken, pasta, and croutons. Gently toss. Pour 1½ cups of the dressing over the top and toss until evenly coated. Add more dressing as needed. Garnish with extra croutons and Parmesan shavings.
Notes
Chicken: I used 1 pound of boneless, skinless chicken breasts in this recipe.Storage: This salad is best eaten immediately (or same day). Store leftovers for up to 1-2 days.Make-ahead: Many of the salad components can be made ahead of time. Wait until just before serving to toss the salad together.
Wash and dry the romaine, wrap it in paper towels, and store it in a plastic bag for up to a week. Wait to chop the romaine until you are ready to assemble the salad.
Bake the chicken breasts and store them for 3-4 days until ready to use. For a shortcut, use a rotisserie chicken.
Blend up the dressing and store it in the refrigerator for up to one week.
