Preheat the oven to 425F. Line a baking sheet with tin foil, and place a baking rack over the foil.
Mix together the salt, milk, and egg white. Whisk gently to combine. In a separate dish, mix the bread crumbs and parmesan with your fingers.
Dredge each piece of chicken in the milk mixture then the parmesan mixture, pressing the coating so it sticks to the chicken. Place the chicken pieces on the baking rack set inside the pan.
Spray the top of the chicken wit cooking spray and bake until lightly golden, 7 - 10 minutes. Remove from the oven, flip the chicken, and spray the opposite with cooking spray.
Return the chicken to the oven and continue to bake until just cooked through 5- 7 more minutes. Time will depend on how thick your chicken is - you may want to cut into a piece to check. If the chicken cooks through before the coating browns, broil it for 30 seconds or so to crisp the panko and parmesan.
Serve as desired. Enjoy!
