Place chicken breasts into a storage bad and pound with meat mallet or rolling pin to about a 1/2 inch thickness.

Cut chicken breasts into halves or thirds depending on the size.

Place chicken back into storage bag and pour in pickle juice.  Let marinate in the refrigerator for at least 30 minutes.

In a medium bowl, beat egg and the milk until completely combined.

In another bowl, combine flour and all spices.

Dip chicken pieces into egg mixture and then into flour mixture, completely coating each piece.  Shake off any excess flour.

Spray the bottom of your Air Fryer with oil.

Place chicken into air fryer and spray the top of each piece of chicken with oil.

Cook at 370 degrees for 12 minutes.  Halfway through cook time, carefully flip chicken and spray top of each piece with oil.  Cook for remaining 6 minutes.

Raise the temperature to 400 degrees and cook for an additional four minutes, flipping halfway through.

Serve on toasted buns, with pickle chips and a small dollop of mayonnaise, if desired.
