Preheat oven to 400°. Place cornflakes, parsley, salt, garlic powder and pepper in a blender; cover and pulse until finely ground. Transfer to a shallow bowl; stir in bread crumbs and pecans. Place milk in another shallow bowl. Dip chicken in milk, then roll in crumb mixture to coat.
Place on a greased baking sheet; spritz chicken with cooking spray. Bake 12-16 minutes or until chicken is no longer pink, turning once halfway through cooking.
