Make the salad base (unless you have some prepared in the fridge - click the ingredient above for link), and set aside to cool. When cool, proceed with recipe.
Put all the ingredients in a food processor or in a blender and press "whiz" until blended.
When you are ready to assemble the salad, wash and dry the romaine lettuce leaves. Toss with about 3/4 of the salad dressing. Reserve the other 1/4, and use only if needed.
Then, toss with the parmesan cheese and black pepper and serve.
