Now, there are two ways to go about this step. The first way is to hard boil the eggs and then peel the shell from them. To hard boil eggs, boil water and then place the eggs in it. Leave them in there for 3-6 minutes and then take them out. Momma doesn't do that though, because she buys the eggs already boiled and peeled (since she "is not a good eggshell-peeler").
Cut the eggs in half and put the yolk into a bowl.
Chop the yolks as finely as you can get them.
Mix in the mayonnaise, mustard, salt, pepper, and garlic salt to the chopped up egg yolk. There aren't any measurements, so just taste as you go.
Put the yolk mix into the eggs that you cut in half.
Sprinkle with the Cajun seasoning.
P.S. In case you were counting the eggs, some where in between steps one and five, a spider jumped from the ceiling and landed on a couple eggs so we threw them away. Even the spiders want to eat them!
