Marinate the turkey steaks in a marinade of rapeseed oil, white wine, salt, pepper, basil and lemon juice for 30 minutes.
Turn the drained steaks in flour and fry them for two to three minutes on each side in two tablespoons of butter and keep warm.
Clean, wash and chop mushrooms and fry each type of mushroom with diced onion in a tablespoon of butter. Season with salt and pepper and sprinkle with chopped parsley and serve with the steaks.
