In a bowl, combine the olive oil, garlic powder, paprika, salt, and black pepper. Add the chicken breasts and coat them evenly with the marinade. Let it sit for 10 minutes.

In another bowl, toss the broccoli, bell peppers, zucchini, and Italian seasoning together until well coated.

Preheat the air fryer to 380°F (193°C). Place the marinated chicken breasts in the air fryer basket and cook for 10 minutes.

After 10 minutes, add the seasoned vegetables to the basket with the chicken. Cook for an additional 10 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender.

Remove the chicken and vegetables from the air fryer. Let the chicken rest for a few minutes before slicing. Serve warm.
