Mashed Potato Salad
Cook potatoes in water to cover until tender, about 20 minutes. Drain potatoes and cool slightly and then mash each potato once with potato masher. Mix in the mayo, eggs, celery seed, cider vinegar, onion, and mustard. Salt as desired. Place small sprigs of fresh parsley on top of the potato salad around the edge of the bowl for decoration. Refrigerate.
