Bake pastry at 425° for 10 to 12 minutes or until it begins to brown. Remove from oven, and gently press handle of a wooden spoon into center of each pastry, forming tart shells.
Spoon 1/2 teaspoon preserves into each shell; top with a cheese cube and a pecan half. Bake 5 more minutes or until cheese melts; serve immediately.
