Cook the tagliatelle in salted water according to the instructions on the packet until al dente and drain. Peel and dice the garlic and onions. Chop the rocket and set aside.
Season onions and garlic with salt and pepper and sauté in olive oil. Then deglaze with the chicken stock and reduce. Cut the turkey breast into strips and add. Let it steep for a moment and fold in the cream and the previously chopped rocket.
