In this one-pan dinner, Italian seasoning infuses the chicken and potatoes with aromatic herbs as they roast.
Preheat oven to 425°F. Toss chicken, potatoes, onion and bell pepper with oil in large bowl. Sprinkle with Italian seasoning and seasoned salt; toss to coat well.
Arrange chicken and vegetables in single layer on foil-lined large shallow baking pan sprayed with no stick cooking spray.
Roast 30 minutes. Turn chicken and stir vegetables. Roast 15 minutes longer or until chicken is cooked through and vegetables are tender.
