Hard boil eggs, cool, peel, and slice lengthwise into halves. Scoop out yolks into a bowl. Place egg white halves on a serving plate.
While eggs are cooking, drain kimchi and save the "juice" in a separate bowl. Very finely chop kimchi.
Using a fork, mash cooked egg yolks with mayonnaise; the mixture might seem a little dry which is okay. Add chopped kimchi and stir well. Add a little bit of the kimchi "juice" at a time until the yolk mixture is a creamy consistency. If the mixture still appears dry, add a little more mayonnaise.
