In a separate shallow pan or dish, whisk together the buttermilk and hot sauce. In a third shallow pan or dish stir together the crispbread crumbs and Parmesan. Set the dishes and a large plate in a row, assembly-line fashion. Dip the chicken in the flour mixture, then in the buttermilk mixture and finally in the crumb mixture, turning to coat at each step and gently shaking off any excess. Using your fingertips gently press the crumb mixture so it
adheres to the chicken. Place the chicken on the plate. Cover and refrigerate for 30 minutes to 4 hours.
