Super Potato Salad

12 medium potatoes cooked with skins on
6 hard-boiled eggs
1 cup mayonnaise
½ cup plain yogurt or sour cream
1 medium onion chopped
1 ½ teaspoons mustard

Boil the potatoes. While they are cooking make the dressing. Peel the eggs, mash the yokes and dice the whites. Add the egg yokes to the wet ingredients, if the dressing is too thick milk can be added. Peel the potatoes and dice. Pour the dressing over the warm potatoes and add diced egg whites. Chill well. It does not taste good warm. Serves six.
