Peel the hard-boiled eggs and cut them in half lengthwise. Remove the yolks and place them in a mixing bowl.

Mash the yolks with a fork, then add mayonnaise, Dijon mustard, white vinegar, salt, black pepper, and chives. Mix until smooth.

Spoon or pipe the yolk mixture back into the egg whites.

Set up a breading station with three bowls: one for flour, one for beaten eggs, and one for breadcrumbs mixed with paprika.

Dip each stuffed egg half in flour, then in the beaten eggs, and finally in the breadcrumb mixture, ensuring they are well coated.

Heat vegetable oil in a frying pan over medium heat. Once hot, carefully add the coated egg halves, frying in batches if necessary.

Fry until golden brown, about 2-3 minutes per side. Use a slotted spoon to remove them and drain on paper towels.

Serve the fried deviled eggs warm, garnished with additional chives or paprika if desired.
