Preheat your air fryer to 400°F (200°C) to ensure a crisp texture.
Cut the chicken breast into uniform 1-inch bite-sized cubes for even cooking.
Chop the broccoli into small florets and the red bell pepper into 1-inch squares.
In a large mixing bowl, combine the chicken cubes, broccoli florets, and chopped bell pepper.
Drizzle the extra virgin olive oil over the mixture and sprinkle with garlic powder, onion powder, smoked paprika, dried oregano, sea salt, and black pepper.
Toss the ingredients thoroughly until the chicken and vegetables are evenly coated with the oil and spice blend.
Transfer the mixture into the air fryer basket, spreading it out into a single layer to allow for proper airflow.
Air fry for 12-15 minutes, shaking the basket halfway through the cooking time, until the chicken is cooked through and the vegetables are tender with slightly charred edges.
Remove from the air fryer and serve immediately while the chicken is hot and the vegetables are perfectly roasted.
