Cut the hard boiled eggs in half. Remove the yolks and set the white parts aside. In a small bowl, combine the yolks with the other ingredients (based on which version you are making) and mash together well. Fill each egg half with the filling and if using a topping like paprika or black pepper, sprinkle on the top. Chill until ready to serve. These are best the day they are made but can be refrigerated (covered well) overnight.
