Lemony Potato Salad With Olives, Corn and Cashews

4 pounds of small red potatoes , Cook until just tender, Do not overcook!
When cooled quarter them and chill while you make the dressing;
Combine 1 Tbsp minced lemon zest
1/2 ounces if lemon juice,
2 Tbsp Dijon mustard,
1 Tsp fresh tarragon { or 1 Tsp dried}
1/2 cup chopped green onions.

Whisk well and slowly drizzle in 1/3 cup of olive oil whisking the whole time. Add 1/8 Tsp red pepper Salt and Pepper to taste. In a large salad bowl place in the quartered potatoes and gently add 1 and 3/4 cup of corn, {fresh or frozen well drained} 1/2 cup pitted chopped Kalamata olives 1/2 cup lightly chopped unsalted cashews, and 1/2 cup chopped parsley. Reserve a little for the garnish. Slowly add the dressing Do not over handle the potatoes or they will break apart. I like to make the dressing ahead of time so it has time for the flavors to develop well.  Makes about 12 servings;
