1–2 pickled banana peppers (or jalapenos if you like)
1/4–1/2 teaspoon cayenne pepper for spicier eggs
6 green olives with pimentos
Slice the eggs lengthwise in half, using a sharp, non-serrated knife.. Rinsing your knife in cold water between eggs will make slicing easier.
Pop the yolks out and set aside.
Put the whites in a container and cover with the beet juice. Let sit for 5 minutes for a light pink color, and up to 24 hours for a dark purple color (I like the longer soak time for more flavor and color, plus a firmer texture).
Mash the yolks with a fork. They will seem crumbly and dry. No worries.
Add the mayonnaise, mustard, peppers, cayenne, and a little of the pepper juice if you like. Mash to make a very smooth, silky paste.
Use a small spoon to fill each egg white cup with a mound of the yolk spread.
Slice the green olives in half and press into each mound to make the demon eye pupil.
