In small bowl, combine lime juice and olive oil. Dip each chicken part in mixture, covering completely. On foil-lined baking pan, arrange chicken in single layer; sprinkle with salt and pepper. Arrange oven rack at least 6 inches from heat and set temperature to broil. Broil about 15 minutes; turn and pour remaining lime-oil mixture over chicken. Broil about 15 minutes more, until fork can be inserted into chicken with ease. Pour mushrooms over chicken and return to oven for about 2 minutes, until mushrooms are hot.
