Preheat the air fryer to 400°F (about 200°C).
In a large mixing bowl combine the chopped chicken, broccoli, cauliflower, zucchini, red bell pepper, and red onion.
Add the minced garlic, olive oil, balsamic vinegar, garlic powder, onion powder, smoked paprika, chili powder, dried basil, and salt and pepper; toss until everything is evenly coated.
Arrange the chicken and vegetables in a single layer in the air fryer basket; avoid overcrowding (work in batches if needed for a small air fryer).
Air fry for 10–15 minutes, shaking or tossing the basket halfway through, until the chicken is cooked through and the vegetables are browned and tender.
Remove from the air fryer and serve warm; optionally serve with rice or noodles.
