Cut your hard boiled eggs in the top section of the egg in zig zags. I used a pairing knife to make it quick work. Scoop out the yolks and add the other ingredients. Whip until smooth. I put the mixture in a small ziplock back. Squeeze all the mixture to one bottom corner of the bag and cut the very tip. This makes it easy to "pipe" the yolks into the eggs.
Use diced olives for eyes and shredded carrots for the nose. Fun, easy and delicious!
