Sriracha Mayo:
In a small bowl, combine all ingredients. Refrigerate until ready to use.
Chicken Sandwiches:
In a large bowl, combine pickle juice, and buttermilk. Add chicken breasts and refrigerate for 30 minutes.
In a separate large bowl, add flour, garlic powder, paprika, and salt, pepper; stir to combine.
Spray the air fryer basket with oil.
Remove the chicken from the marinade and dredge breasts in the flour mixture. Place the chicken in the air fryer basket. Spray the top of the chicken with a little oil. Air fry at 400 degrees for 15 minutes.
Open the air fryer and turn the chicken using tongs. Be careful not to lose any of the breading. Spray the other side of the chicken. Air fry for an additional 5-7 minutes or until the chicken is crisp. Remove the chicken from the air fryer and assemble the sandwiches. Enjoy!
