Boil eggs very hard and cut into halves

Separate the yolks from the white. Put the yolk in a bowl

Add black pepper (according to desire)

Add some mayonnaise

Mash up using a spoon, add extra mayonnaise if necessary

Put the yolk mixture into a piping bag, you can use nylon if you don't have a piping bag, I used nylon

Cut the sharp edge of the nylon and pipe the yolk mixture into the egg whites.

Sprinkle some black pepper on it

Garnish with mint leaves... Your Deviled eggs are ready! Enjoy!
