Arrange potatoes end to end in a circle on paper towels in microwave oven, leaving at least 1 inch between each potato.

Mash pulp, and set aside.
Place cream cheese in a medium-size glass mixing bowl.
Microwave at MEDIUM LOW (30% power) for 1 minute or until softened.
Add potato pulp, milk, and parsley; mix well.
Stuff shells with potato mixture, and place on a microwave-safe serving platter.
Microwave at HIGH 5 minutes or until thoroughly heated, giving dish one half-turn after 3 minutes.
Serve with Bechamel Sauce.
