1. Slice the chicken into six fillets, pound them to ¼ inch thickness between plastic wrap, and season evenly with salt, pepper, Italian seasoning, herbes de Provence, and garlic powder.
6. Add garlic and white wine or chicken stock, cook until reduced, then stir in flour, cook for 1-2 minutes, add broths and bouillon, boil, simmer for 3-5 minutes until thickened, and remove from heat.
7. If skillet isn't oven-safe, transfer sauce to a casserole dish, add chicken and cheese, and bake at 475°F for 10-15 minutes until cheese is golden and bubbly.
