Preheat the oven to 425F, and place the rack in the upper third of the oven. Place a wire cooling rack over a large baking sheet. Spray the sheet with non-stick spray. If you don't have a cooling rack, line the baking sheet with foil and spray it. See Notes
Combine everything except the salt and pepper. Add a good pinch of each. Taste and re-season as desired. Chill till needed.
You can use a gluten free cup for cup blend, or straight Cassava or Coconut flour.
Avoid using packaged in a can parmesan, it has the wrong texture, and no flavour. It will not help in the crisping process
Feel free to replace the parmesan cheese with finely chopped nuts, crushed corn flakes, crushed pretzels.
If not using a wire rack, turn the chicken pieces half way through the baking process.
Other dip options: BBQ, Ranch, Tzatziki, or even good ole ketchup!
Leftovers can be stored in a sealed container in the fridge for 3-4 days. Re-heat in a toaster oven or oven, not the microwave. Set heat at 350F and heat till warmed through.
