In a medium bowl, whisk together the Dijon mustard, lemon juice, Worcestershire, mayonnaise, minced garlic and anchovy paste until well combined. Stir in the grated Parmesan cheese and ¼ teaspoon pepper then set the dressing aside while you make the salad.

Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, about 10 minutes. Drain the pasta and transfer it to a large serving bowl.

Cut the Romaine hearts into 1-inch pieces then add them and your protein of choice to the bowl with the pasta.

Add the prepared dressing and toss to combine. Add the croutons (optional) and garnish with Parmesan cheese. Serve immediately or refrigerate, covered, until ready to serve.
