Boil the turkey fillet in salted water until tender. Mix apple cider jam with a pinch of nutmeg and a pinch of cinnamon. Add lemon juice.
Grease all pieces of bread with butter on one side and apple jam on the other.
Place the thinly sliced turkey on the jam side on half of the bread. Sprinkle with pepper.
Place thinly sliced cheese on top of the turkey.
Tear the arugula with your hands and scatter over the cheese.
Cut the apple in half, core it, chop thinly and spread over the arugula.
Cover with the second slice of bread, the side smeared with jam, over the apples.
Fry the turkey-apple sandwich in a skillet under the lid until golden brown on one side. Then turn the hot turkey sandwich over and fry until golden brown on the other side.
Toast with turkey, cheese, arugula and apple is ready.
