Deviled eggs are a quick and easy appetizer that anyone can make—it’s as simple as boiling water! Plus, these savory treats are packed with protein and flavor.
Remove shells from hard-boiled eggs and slice in half lengthwise. Carefully remove the yolks, and transfer to a bowl.
Using a fork or pastry blender, mash the yolks. Add mayonnaise, mustard, cayenne pepper, celery, onion, salt, and black pepper to taste.
Spoon filling into a zip-top bag, cut off a corner tip, then pipe into the egg white halves. Garnish with paprika if you like.
Chill and serve.
