Stove top instructions: Heat the olive oil in a large pan over medium high heat. Season the chicken with salt and pepper on both sides. Add the chicken to the pan and cook for 5-6 minutes on each side or until cooked through. Remove the chicken from the pan and cover with foil to keep warm. Add the mushrooms to the pan and cook for 4-5 minutes or until tender. Add the garlic and cook for an additional 30 seconds. Add the marsala wine and chicken broth to the pan and simmer for 5 minutes. Stir in 1 tablespoon of cornstarch that's been mixed with 2 tablespoons cold water. Simmer until just thickened. Stir in the cream and simmer for 2 more minutes. Add the chicken back to the pan and spoon the sauce over the top. Sprinkle with parsley and serve.
