These savory puff pastry pinwheels are filled with ham, cheese, and herbs. The puff pastry is flaky and buttery, while the filling is salty and cheesy. To make them, simply roll out the puff pastry, spread some Dijon mustard on top, then layer on some ham and cheese. Sprinkle with herbs, roll up the pastry, and slice into pinwheels. Bake until golden brown and crispy.
