Hard-boil the eggs, let them cool, and peel carefully. Slice in half lengthwise and remove yolks.
Mash yolks with mayonnaise, Dijon mustard, vinegar, paprika, salt, and pepper until smooth.
Stir in orange food coloring (or natural option) until the mixture turns pumpkin orange.
Pipe or spoon filling back into egg whites, shaping into small mounds.
Use a toothpick to create vertical “pumpkin” lines.
Insert a small piece of chive, parsley stem, or celery in the center as the pumpkin stem.
Arrange on a platter, sprinkle with paprika, and serve chilled.
