Radicchio leaves or other red or bronze-colored lettuce leaves
Directions:
Remove strings from celery and cut into thin diagonal slices. Reserve a few celery leaves.
Cut parmesan cheese into paper-thin slivers.
Coarsely chop walnuts.
Core and thickly slice pears. If not using immediately, toss pears with a little lemon juice to prevent discoloration.
Place celery, cheese, walnuts, and pears into a bowl. Drizzle with a little olive oil and lemon juice to taste. Season with salt and pepper and toss very gently.
Line serving platter with radicchio leaves and gently arrange salad on top. Garnish with reserved celery leaves.
