4 bone-in chicken pieces (I usually just cut up boneless skinless chicken breasts - but I think it dries the chicken out a bit. I think next time I will probably just put in the whole chicken breast.)
4 large potatoes, cut into cubes
Preheat oven to 400 degrees. In a large bowl pour Italian dressing and parmesan cheese over chicken and potatoes and mix together. Place chicken and potatoes in a 13X9 inch baking dish. Bake 45 minutes to 1 hour, or until chicken is cooked through and potatoes are tender.
