Crisp and fresh: radish and celery root salad

Flipping through a recent Donna Hay magazine, I came across a radish and celery root salad that looked divine. I adore celery root - its crunchy, sweet, essence-of-celery taste is divine. I love it in soups but I'd never tried it raw. Donna's recipe called for a thick, heavy dressing of largely full-fat mayonnaise. Donna - what were you thinking? So I made my own interpretation. This is fresh from the farmer's market - hope you are inspired.

Radish and celery root salad (inspired by Donna Hay)

8 radishes, thinly sliced with a mandoline
One large celery root, peed and cut into pieces a bit larger than matchsticks
Chopped chives (note: you can also used other herbs instead or in addition to the chives, such as chopped Italian parsley and chopped chervil)
One cup plain low fat Greek yogurt
One clove garlic, minced
1 Tbs good olive oil
1 Tbs champagne vinegar
1 wedge of lemon
Salt and freshly ground black pepper

Combine yogurt, garlic, olive oil and vinegar with a couple of pinches of salt and pepper. Squeeze lemon wedge into mixture. Adjust seasonings as necessary. Set aside.

Put a portion of celery root on each plate and top with radish slices. Drizzle with dressing. Sprinkle with herbs. Serve immediately.
