Whisk salad dressing ingredients until combined, then set aside.

Using a mandolin or sharp chef's knife, slice zucchini lengthways into long strips.

Use 1 sliced zucchini per serving.

Curl zucchini strips around two fingers until you make a tube then place on a plate.

Continue to do this until you have used up all of your zucchini strips, arranging in an appealing shape on each plate.

Make sure the zucchini tubes are pushed together so they stay intact.

Place onion rings over and on top of zucchini then sprinkle with goat cheese.

Whisk salad dressing a little before drenching salad with it.

Garnish with watercress.

Serve immediately.
