In a small bowl, mix cream cheese, spinach, parmesan, tomato, garlic, ¼ teaspoon pepper, and ⅛ teaspoon salt.
Slice a deep pocket into the side of each chicken breast.
Fill each pocket with the cream cheese mixture and secure with toothpicks.

Preheat air fryer to 375°F (190°C).
Place chicken in the air fryer basket, ensuring they don't touch.
Cook for 15-17 minutes until internal temperature reaches 165°F (74°C).
Let rest 3 minutes, remove toothpicks, and serve.
