Preheat oven to 400°. On a lightly floured surface, unfold puff pastry. Roll pastry to a 12-in. square; cut into sixteen 3-in. squares. Place 1 teaspoon preserves in center of each square; top with ham, folding as necessary, and cheese. Overlap 2 opposite corners of pastry over filling; pinch tightly to seal.
Place on a parchment-lined baking sheet. Bake 15-20 minutes or until golden brown. Cool on pan 5 minutes before serving. If desired, serve with additional apricot preserves.
Freeze option: Freeze cooled pastries in a freezer container, separating layers with waxed paper. To use, reheat pastries on a baking sheet in a preheated 400° oven until heated through.
