Preheat oven to 450°. Spray a large baking sheet lightly with spray.
Combine breadcrumbs, Fiber One, and Parmesan cheese in a bowl. Melt the butter in another bowl. Lightly brush the butter onto the chicken, then dip into breadcrumb mixture.
Place on baking sheet and repeat with the remaining chicken. Lightly spray a little more cooking oil on top and bake in the oven for 20 minutes. Turn chicken over, bake another 5 minutes. Remove from oven, spoon sauce over chicken and top with shredded cheese. Bake 5 more minutes or until cheese is melted.
