Filling
Slice the eggs in half lengthwise and gently remove the yolks, placing them in a bowl. Set the whites aside. Mash the yolks with a fork until fine and crumbly. Add the mayonnaise, Dijon mustard, vinegar, salt, and pepper, then mix until smooth and creamy. Taste and adjust seasoning as needed.
3. Fill the Egg Whites
For a polished look, spoon the filling into a piping bag fitted with a star tip (or use a zip-top bag with the corner snipped). Pipe the mixture neatly into each egg white.
For a more relaxed presentation, simply spoon the filling in.
4. Garnish
Dust lightly with paprika for color and subtle flavor. Sprinkle with chopped chives or your choice of optional toppings, such as crispy bacon.
5. Serve
Arrange on a platter and refrigerate until ready to serve.
