Fill up a large saucepan with your 12 eggs and cover the eggs with at least an inch of cold water, preferably two inches. Bring the water to a rolling boil. Cover, and remove from heat. Let sit covered for 10-12 minutes.
Drain hot water from pan and run cold water over the eggs. Let them sit in the cool water a few minutes.
Peel the eggs. Once peeled, slice each egg in half, lengthwise. Gently remove the yolk halves and place in a small mixing bowl. Arrange the egg white halves on a serving platter.
Using a fork, mash up the yolks and add mustard, mayonnaise, onion, Tabasco, and a sprinkling of salt and pepper. Add more mayonnaise as necessary to get to the creamy consistency you want.
Pipe through a piping bag (star tip) or simply use a spoon to put the egg yolk mixture into the egg white halves. Sprinkle with paprika and decorate with parsley as desired.
