This is a unique recipe for a different potato salad. For Weight Watchers -- it has 4 points per serving. I cooked white and sweet potatoes together and tested their doneness at intervals. Added frozen corn at last minute. The only change I made to the recipe was to add some curry powder --- made all the difference in the world....picked up the flavors of sweet potatoes, as well as other vegetables. I will be making this recipe for a long time.
