To make deviled eggs you must first start with making boileed eggs. To hard boil eggs you drop eggs into bolilingwater and let them boil for about 20 minutes. When they are finished put them in a sink or bowl filled with cool water. Next you will peel the shells off of the boiled eggs. After this is done, cut the eggs in hlaf longways. Scoop out the egg yolks and place them in a bowl and save the empty egg whites.
The next step will be to mix mayonaise, salt, pepper, and onions with the egg yolks. Mix all this up until it is made into a smooth filling that you can fill the holes in the whites with. Scoop a bit of the mixture into each half of emplty egg whites, chill, and enjoy.
