Preheat oven to 350° F. Roll out thawed puff pastry sheet and cut into 6-8 squares. Place squares on baking sheet in one layer. Take a glass or mason jar lid and gently indent the center of each square. Spread about 1 tablespoon of goat cheese into each circle. Top with dates, pecans and finally rosemary. Bake for about 10-12 minutes or until golden.
