Fennel, Red Onion, and Parsley Salad

Prepare a large ice-water bath. Put parsley, fennel, and onion in a colander, and set in ice-water bath. Let soak 10 minutes.

Drain, and transfer to a salad spinner. Spin until dry, and transfer to a serving bowl. Add lemon juice, oil, and celery seeds; toss to combine. Season with salt and pepper.
