Use a mallet or rolling pin to pound out the chicken breast to 1/2 inch thickness.
Crack the eggs into a shallow baking dish. Beat in the water. Place the pork panko (or powdered Parmesan) in another shallow baking dish, add basil and pepper, and mix until well combined.
Dredge chicken in the eggs and let any excess drip off, then dip both sides of the chicken in the pork panko mixture. Spray the coating with Primal Kitchen Avocado Oil Spray.
Set the coated chicken into the air fryer and cook for 10 minutes, flipping after 5; or until chicken is cooked through and no longer pink inside.
Meanwhile heat the Primal Kitchen sauce in a small sauce pot over medium heat. Place 1/2 cup of sauce on each plate.
Serve the chicken immediately on the marinara sauce. Garnish with fresh basil leaves.
Store the chicken in an airtight container in the refrigerator for up to 4 days. To reheat, place in air fryer at 390 degrees F for 5 minutes, or until heated through.
