Combine the ingredients for the dressing in a medium bowl and mix well. You can also make the dressing in a food processor.
Taste and adjust seasoning if necessary. You want the dressing to be punchy in flavor and slightly over-seasoned as the lettuce, pasta and croutons are all relatively bland.
Bring a large pot of salted water to a boil then add the tender pasta and cook for 10-12 minutes or until al dente.
Drain and rinse with cold water then add to a large mixing bowl.
Add the lettuce, croutons, parmesan shavings and dressing to the pasta and toss to combine then serve.
