Step 1

Place the eggs in a saucepan, and cover them with cold water. Bring the water to a boil and immediately remove it from the heat. Cover, and let eggs stand in hot water for 18-20 minutes. Remove the eggs from the hot water, and cool by rinsing eggs under cold running water until cool.

Step 2

Peel the hard-cooked eggs, and cut them in half lengthwise. Remove yolks to a small bowl. Mash egg yolks. Add mayonnaise and pesto to the egg yolk and mix well.

Step 3

Evenly fill the egg white halves with the yolk mixture.

Step 4

Refrigerate until serving.
