Place the eggs in a pot and cover with water. Bring to a boil, then cover and remove from heat. Let sit for 10 minutes.

Transfer the eggs to an ice bath to cool for 5 minutes, then peel and slice in half lengthwise.

Remove the yolks from the egg halves and place in a mixing bowl. Mash the yolks with a fork.

Add mayonnaise, Dijon mustard, salt, black pepper, and hot sauce (if using) to the yolks. Mix until smooth.

Add black food coloring to the yolk mixture and mix until the desired color is achieved.

Spoon or pipe the black yolk mixture back into the egg whites.

Top each egg with a slice of black olive to resemble a dragon eye and sprinkle with chopped chives.
