4 to 5 crimini mushrooms or button mushrooms, sliced

1/2 teaspoon finely chopped fresh rosemary

1/4 teaspoon freshly ground black pepper

1 large egg, lightly beaten

3. Roll 1 puff pastry sheet into a 9- x 12-inch rectangle on a lightly floured work surface. Cut into 12 (3-inch) squares. Spread about 1/2 teaspoon Boursin cheese and 1 mushroom slice in the center of each pastry square, Top with 1 beef cube and sprinkle with a pinch of sea salt .
