Season the turkey with salt and pepper and poultry seasoning. Set up a breading station of flour, then egg then bread crumbs. Bread cutlets and reserve them.
Combine parsley, celery, scallions, apple, mushrooms and dress with salt, pepper, the juice of 2 lemons, 3 tablespoons olive oil. Butter toasted bread then chop into 1/4 inch dice. Toss bread and thyme into salad. Dampen the stuffing salad a bit with apple cider or juice and toss to combine.
Melt 3 tablespoons of butter over medium heat in medium saucepan. Add flour and cook 1 minute then whisk in stock, season with salt and pepper and Worcestershire and thicken stock a few minutes over medium-low heat.
Heat 2 tablespoons olive oil in a large skillet over medium-high heat, cook cutlets 10 minutes turning once. If the pan is too small to cook all 4, reserve 2 under foil and add another tablespoon olive oil and cook off remaining cutlets.
Serve cutlets on raw stuffing salad and top with warm gravy.
