Peel the hard boiled eggs and cut them in half lengthwise. Scoop out the yolks and put them in a bowl. Set egg whites aside.
In another small bowl, combine mayonnaise, onions, dijon mustard and spices. Stir in 2 drops of red food coloring and 1 drop of yellow food coloring.
Add the mayonnaise mixture to the egg yolks. Mix well until the yolk mixture is smooth, creamy and a consistent orange color.
Place the yolk mixture into a disposable piping bag fitted with a large star tip.
Pipe the filling into the hollow of the egg halves. Add a chive to the top of the egg for the pumpkin stem.
Place the eggs on a serving platter and enjoy!
Notes
I used gel food coloring for this recipe but you can use liquid food coloring as well, just make sure it is food safe.
If you don't have a piping bag, you can transfer the egg yolk mixture into a ziploc bag, squeeze the air out and seal the bag. Using scissors, cut off a corner of the bag and squeeze the mixture into the eggs to make the pumpkin design.
You can definitely make these deviled eggs ahead of time. Boil the eggs, prepare the yolk mixture and store them in the refrigerator. When you are ready to make the eggs, allow the yolk to soften up a bit, pipe the filling, add the chives and serve.
