Shell your hardboiled eggs, slice them in halves and plop out the yolk into a bowl. Place the eggs on a serving tray.
Smash the yolks with a fork in the bowl.
Add into the bowl, mayo, mustard, salt and pepper and mix.
Once the yolk mixture is to your liking[you can try it, add more anything you just added to get it to your liking!] Spoon the mixture into empty eggs.
Sprinkle the filled eggs with paprika & enjoy!
