Peel the hard boiled eggs, slice them in half, and scoop the yolks into a small mixing bowl. Set the egg white halves onto a platter.

Mash the egg yolks with a fork.

Add the mayonnaise, mustard, vinegar, salt and pepper to the bowl, and stir to combine until smooth. Optional – if you'd like the mixture to be more orange than yellow, add one drop of red food coloring and mix.

Add the egg yolk mixture to a piping bag with the piping tip of your choice.

Pipe the yolk filling into the egg white halves to form circles for the pumpkins.

Use a toothpick to lightly draw lines into the 'pumpkins'.

Slice a few chives into ¼-½ inch pieces.

Place the chive pieces onto your egg pumpkins as stems.

Sprinkle with paprika.

Chill in the refrigerator in an airtight container until ready to serve.
