Preheat oven to 350°. In a small bowl, beat the spreadable cheese, milk and eggs. Place tart shells on an ungreased baking sheet; fill each with 2 teaspoons mixture. Sprinkle with parsley.
Bake for 10-12 minutes or until filling is set and shells are lightly browned. Sprinkle with chives if desired. Serve quiches warm.
