In a sauce pan, cover six eggs with cold water and bring to a boil. When the water is boiling, turn off heat, cover, and let the eggs sit in the water for 12-15 minutes.
While the eggs are cooking, chop the celery, scallions and parsley.
With a slotted spoon, remove the eggs from the water and place directly into an ice bath. Peel the eggs and chop.
Mix all the ingredients in a large bowl. If desired, place the bowl in the refrigerator to chill.
