Directions

1. Scrub potatoes and place in a large saucepan. Cover with water and boil until tender, about 30 minutes. Drain, cool slightly, peel and slice into 1/2-inch rounds. Stir together next eight ingredients; set aside. Place one-third of potato slices in a large bowl; spread with one-third of the dressing mixture. Arrange one-third onion over dressing, one-third radishes and sprinkle with one-third parsley. Repeat layers twice with remaining ingredients.
