Add 6 eggs in boiling water and let cook for 8 minutes on high heat

Peel the eggs, cut in halfs and take out yolks

Put yolks in a blender, add peeled avocado and mustard and blend for few seconds (or you can press and mix all together with a fork)

Put the whites on serving plate and fill them back with the yolks with mustard and avocado

Sprinkle with chili powder (or any other spice you like) and serve
