3 to 4 stalks celery heart
3 ounces Parmesan cheese
Small handful walnut halves
3 large firm-ripe pears
Extra-virgin olive oil
Freshly ground pepper
Radicchio leaves or other red or bronze-colored lettuce leaves
1. Remove strings from celery and cut into thin diagonal slices. Reserve 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 little lemon juice to prevent discoloration.
2. Combine celery, cheese, walnuts and pears in bowl. Drizzle with a little olive oil and lemon juice to taste. Season to taste 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.
