Peel the hard boiled eggs and cut eggs in half lengthwise. Add two of the egg yolks to a medium bowl; discard the remaining yolks. Add avocado and mash with a fork or potato masher. Gently stir in lime juice, red onion, tomato, cilantro, salt and pepper. Adjust seasonings to taste.
Place egg halves on a platter and scoop guacamole evenly into each halve. Sprinkle with a little additional chopped cilantro and serve.
