Cover the roulades with ham and sage, season with pepper, roll up and stick together with wooden sticks. Heat the butter in the pan and fry the roulades brown all over. Pour in the white wine and cream and stew everything in the pan for about 10 to 12 minutes. Now take the turkey rolls out of the pan and keep warm. Stir the mustard and capers into the sauce and thicken with a sauce thickener until the desired consistency is achieved. Place the roulades in the sauce and serve.
