Chop and clean your Romaine, I highly recommend buying a plastic lettuce knife. No more rusty lettuce!
Two handfuls will probably feed two people, but use however much lettuce you want. The dressing works for up to an entire head of lettuce. Add your lettuce to your serving bowl
Sprinkle the parmesan over the lettuce (it might seem like a lot but just trust me)
Add oil, vinegar, lemon juice, garlic and Worcestershire to a glass measuring cup (sometimes I just use a coffee mug) and give it a good stir. I use a fork.
Add salt and pepper, to taste, stir vigorously.
Dress lettuce right before serving. Make sure you give the dressing one good last stir before doing so.
