Prepare the Chicken: In a large bowl, combine the chicken cubes with the Italian dressing, adobo seasoning, dry Italian herbs, kosher salt, and optional Sazon seasoning. Stir well to ensure each piece of chicken is evenly coated.

Preheat the Air Fryer: Preheat your air fryer to 400°F for 5 minutes. Spray the air fryer basket with a light coat of cooking spray to prevent sticking.

Cook the Chicken Bites: Place the seasoned chicken pieces in the air fryer basket in a single layer. Depending on your air fryer size, you may need to cook the chicken in batches. Air fry at 400°F for 12 minutes, shaking the basket halfway through cooking.

Check for Doneness: After 12 minutes, check that the chicken is browned and cooked through. If necessary, add a few more minutes of cooking time to achieve the desired level of crispiness.

Serve and Enjoy: Once done, remove the chicken from the air fryer and serve immediately with your favorite dipping sauce or a side of vegetables.
