American Style Potato Salad with Eggs and Sweet Relish Serves 6-8

For the 4th of July party I had, I made, along with the brats, burgers and wings, this terrific true blooded American potato salad.  I also made it for our book club cook out and everybody loved it.  How can you go wrong with potatoes, mayo relish and egg?  I think this is from Cook's Illustrated but can't remember where I found it.

American Style Potato Salad with Eggs and Sweet Relish Serves 6-8

3 hard boiled eggs, peeled and cut into small dice
2-3 scallions, sliced thin
1 small celery stalk, cut into small dice (about 1/2 cup)
1/4 cup sweet pickle (they say don't use relish, I did and it turned out fine), cut into small dice
1/2 cup mayo
2 tbls Dijon mustard
1/4 cup chopped fresh parsley

Layer the warm potato cubes in a med. bowl; sprinkle with vinegar, salt and pepper.  Refrig while preparing remaining ingredients.  Mix remaining ingredients and add to chilled potatoes.  Mix well season to taste and refrig until ready to serve.
