Follow these simple steps to create your spooky Halloween deviled eggs:

1. Boil the Eggs: Place the eggs in a pot and cover them with cold water. Bring to a boil over medium-high heat. Once boiling, cover the pot and remove it from heat. Let sit for 10-12 minutes.
2. Cool the Eggs: Transfer the eggs to an ice bath immediately after cooking. Allow them to cool for about 5-10 minutes.
3. Peel the Eggs: Carefully peel the cooled eggs and rinse under cold water to remove any leftover shell pieces.
4. Slice in Half: Cut each egg in half lengthwise and gently scoop out the yolks into a mixing bowl.
5. Make the Filling: Mash the yolks with mayonnaise, Dijon mustard, and a pinch of salt and pepper until smooth. Add a few drops of green food coloring and mix thoroughly.
6. Fill the Egg Whites: Spoon or pipe the yolk mixture back into the egg whites, making them look whimsical and enticing.
7. Decorate: Cut the black olives in half to create the spiders and place one or two halves on top of each filled egg for decoration. You can also sprinkle a little paprika over the top for added color.
8. Chill: Place the deviled eggs in the refrigerator for at least 30 minutes to allow flavors to blend and to firm them up.
9. Serve: Once chilled, arrange the spooky Halloween deviled eggs on a platter. You can add a garnish of fresh herbs for an extra touch.
