In a small saucepan, combine the preserves, pie spice and 1 tablespoon brown sugar. Cook and stir over medium heat until sugar is dissolved. Spoon into tart shells; arrange on an ungreased baking sheet. Sprinkle with cheese and remaining brown sugar.
Bake at 350° for 5-7 minutes or until cheese is melted. Serve warm. Yield: 15 appetizers.
