Halve peeled hard-boiled eggs lengthwise and scoop the yolks into a medium bowl (save the whites). Using a fork, smash the yolks into a paste and add some mayonnaise, Dijon mustard, saltand pepper. Maybe you like chopped up scallions or pickles in there, too. Who knows? Go crazy. Just make sure it tastes amazing.
Fill a ziplock bag with this ~amazing mixture~ and snip a little hole in the corner. Fill the egg whites with the yolk mixture, then sprinkle some paprika and chives over the top.
