Shell hard-boiled eggs and cut them in half lengthwise. Remove yolks and mash them to a smooth thick paste with pounded buttered shrimps, mayonnaise and lemon juice, to taste.
Stuff each egg white with shrimp mixture, piling it up to re-form egg shape.
Arrange stuffed eggs on a bed of Green Mayonnaise in an hors-d’œuvre dish. Sprinkle with finely chopped herbs.
