Halve the breast halves lengthways, place them between two plastic sheets and pound them lightly. Season with salt and pepper on both sides. Place three sage leaves on each, wrap a slice of Parma ham around the breast fillets and secure with toothpicks.
Heat the butter in a non-stick pan and fry the schnitzel on both sides until golden brown. Add the Marsala and let it simmer for 15-20 minutes on a very low heat.
Thinly slice or slice the zucchini. Heat the oil in a pan and fry the slices lightly, then pour in a little broth. Season with salt and pepper and add the maple syrup. Put a lid on and cook on low heat for about 10 minutes.
When the cooking time is over, add 3-4 tablespoon of the zucchini stock to the chicken pan and stir in. If you want, you can easily thicken the marsala sauce with a little flour. But also tastes great when not bound.
