In a small bowl, add all of the filling ingredients, mix well.
Start by cutting a pocket into the chicken breast. The easiest way to do this is to put one hand on the chicken breast and use your knife to cut into the center.
Add the filling into the cavity you created.
Place the chicken into the air fryer basket, spray the chicken with olive oil, and set in the air fryer for 10 minutes at 370 degrees F (air fryer setting)
Then take the chicken breasts out, and spray them with olive oil, add some Italian seasoning on top.
Add another 5-7 minutes. Then use a meat thermometer and check the temperature, mine reached 165 degrees F, so I removed the chicken from the air fryer
The time to cook will depend on how thick your chicken is and what air fryer you own.
Allow to rest, for about 5 minutes, before serving.
