Chop the hard-boiled eggs into small pieces and place them in a large mixing bowl.

Add the mayonnaise, sour cream, Dijon mustard, white vinegar, salt, black pepper, and paprika to the bowl.

Using a fork or potato masher, mash and mix all ingredients together until creamy but still slightly chunky.

Fold in the chopped chives and transfer to a serving bowl.

Sprinkle additional paprika on top for garnish and refrigerate for at least 30 minutes before serving with crackers or vegetables.
