Have previously washed your lettuces and spun dry, or put in a large, clean pillow case and swung over your head for a few seconds (this really works! The centrifugal force gets the water off the leaves and the pillow case absorbs it- don't let anyone see you doing this- they'll think you're insane).
Whisk together the dressing ingredients in a small bowl.
Combine the lettuces in a large bowl and toss well.
Add the apples and nuts and drizzle with the dressing.
Using a vegetable peeler or sharp paring knife, shave curls off if a wedge of parmesan over the top (be generous!).
Serve at once as the lettuce will start to wilt with time.
