Preheat oven to 450 degrees. Line jellyroll pan with foil; top with baking rack. Combine mustard, honey, butter and seasoning. Transfer 1/2 cup mustard sauce to small bowl to serve with cooked wings; reserve.
In large bowl, toss wings with 1/2 cup mustard sauce until coated. Arrange wings in single layer on rack in pan. Bake 15 minutes or until lightly browned. Turn wings over; bake 15 minutes.
Brush remaining mixture over wings. Bake until glaze is bubbly and chicken is no longer pink near bone, about 3 minutes. Serve with reserved mustard sauce.
