These delicious puff pastry pockets are filled with tender chicken, mixed vegetables, and a creamy sauce. The puff pastry is flaky and buttery, while the filling is savory and satisfying. To make the filling, sauté some chicken with onions and garlic, then add some mixed vegetables and a creamy sauce made with milk, flour, and herbs. Cut the puff pastry into squares, fill them with the chicken mixture, and bake until golden brown and crispy.
