In a small bowl, mix olive oil, Tuscan seasoning, garlic powder, paprika, salt, and black pepper.

Rub the mixture over the chicken thighs or breasts, ensuring they are well coated.

In a large bowl, toss the diced potatoes with olive oil, rosemary, thyme, salt, and black pepper until evenly coated.

Preheat the air fryer to 400°F (200°C) for 5 minutes.

Place the seasoned chicken in the air fryer basket and cook at 400°F (200°C) for 10 minutes.

Add the seasoned potatoes to the basket with the chicken. Cook for an additional 15-20 minutes, shaking the basket halfway through, until the chicken reaches an internal temperature of 165°F (74°C) and the potatoes are crispy and tender.

While the chicken and potatoes are cooking, toss the sliced bell pepper, zucchini, and cherry tomatoes with olive oil, dried basil, oregano, salt, and black pepper.

In the last 5 minutes of cooking, add the veggies to the air fryer basket with the chicken and potatoes. Shake the basket gently to combine and cook until the veggies are tender and slightly charred.

Remove the chicken, potatoes, and veggies from the air fryer.

Serve immediately, garnished with fresh herbs if desired.
