**Hard-Boil Eggs:** Boil the eggs in a medium saucepan for 9–10 minutes. Once cooked, transfer them to a bowl of ice water to cool. Peel the eggs once cooled.
**Chop or Mash Eggs:** Roughly chop the eggs or mash them with a fork or potato masher, depending on your desired texture.
**Make Dressing:** In a mixing bowl, whisk together the mayonnaise, Dijon mustard, apple cider vinegar, paprika, garlic powder, salt, and pepper until smooth.
**Combine:** Add the chopped eggs to the dressing and gently mix until evenly coated.
**Garnish and Serve:** Sprinkle with additional paprika and chopped chives or green onions, if desired. Serve immediately or chill for 10–15 minutes for enhanced flavors.
