Fennel and Celery Salad

Cut fennel bulbs in half lengthwise, discarding outer layer if it is tough. Slice quarters thinly (using a mandoline if you have one). Slice celery equally thin.

In a medium bowl, toss fennel and celery together. Dress with olive oil and lemon juice, season to taste. Sprinkle with Parmesan and chopped fennel fronds if you wish, and serve.
