Fill a large pot with water and boil the egg for 12 minutes. Then add them to an ice bath bowl for 10 minutes. Chill for 1 hour.
Once chilled, peel the eggs and slice them in half. Then combine the yolks in a small bowl with the mayonnaise, dijon mustard, dill, chives, garlic powder and salt and pepper.
Pipe the yolk mix back into the egg white shells and then top with salmon, capers, thyme leaves, extra dill, extra chives and sea salt and pepper to taste.
Gently cover these and put them in the refrigerator for at least 20 minutes before serving.
