Preheat the oven to 400 degrees. Drain the tropical fruit; lightly chop and add to a medium bowl. Combine the cottage cheese, sugar, ginger and cinnamon in the mixing bowl with tropical fruit; mix until well combined and set aside. Roll out the thawed puff pastry sheets. Cut out round using a 3-inch pastry cutter. Spoon 1 teaspoon of the cottage cheese mixture on the bottom half of the pastry rounds; brush half the dough with an egg wash. Seal the pastry to a half circle and using scissors, cut a vent on the top of the pastry. Sprinkle the top with cinnamon and sugar. Bake for 15 minutes or until golden brown. Allow to cool on wire racks before serving.
