Heat oven to 450°F. Line a baking tray with a wire cooking rack greased with non-stick spray.
Season chicken on both sides with salt and pepper.
Mix melted butter, Dijon mustard and garlic in a medium bowl. In another medium bowl, combine breadcrumbs, cheese, parsley, garlic powder, cayenne, salt and pepper.
Dip chicken into the melted butter mixture, followed by breadcrumbs mixture, pressing to evenly coat.
Place on prepared wire rack, spritz with non-stick spray, and bake for 25 minutes, until golden brown and cooked through. Serve with lemon wedges.
