In a small mixing bowl combine the yogurt, the Philadelphia cream cheese, the pecans, the spring onions, the olives, and the lemon juice. Give this all a good mix and set aside.
Chop off the ends of the chicories and carefully peel off the leaves one by one.
Fill the endives/chicories with Greek yogurt filling and place one anchovy on each chicory boat.
Plate on a round plate and place a small bowl with the remaining sauce in the middle.
