Begin by hard boiling the eggs. Place the eggs in a saucepan and cover with water. Bring to a boil over medium heat, then cover, remove from heat, and let sit for 12 minutes.
Once the eggs have cooked, immediately transfer them to an ice bath to cool for about 5-10 minutes. This will stop the cooking process and make them easier to peel.
After cooling, gently tap the eggs against a hard surface to crack the shell, then peel them under cold running water to help remove the shells cleanly.
Slice the peeled eggs in half lengthwise and carefully scoop out the yolks into a mixing bowl, placing the whites on a serving plate.
To the yolks, add mayonnaise, Dijon mustard, apple cider vinegar, salt, and pepper. Mash together until smooth and creamy.
Mix in 1 tablespoon of everything bagel seasoning, reserving a bit for garnish.
Spoon or pipe the yolk mixture back into the egg white halves.
Sprinkle the tops with the reserved everything bagel seasoning and garnish with finely chopped fresh chives.
Serve chilled or at room temperature for the best flavor.
