Rinse millet under cold water until it runs clear. Drain well.

In a medium saucepan, combine millet and chicken broth. Bring to a boil, then reduce heat, cover, and simmer for 15 minutes, or until the liquid is absorbed. Remove from heat and let it sit covered for 5 minutes.

Preheat the air fryer to 380°F for 3 minutes.

In a bowl, toss the chicken pieces with olive oil, garlic powder, onion powder, paprika, salt, and black pepper until evenly coated.

Place the seasoned chicken in the air fryer basket in a single layer. Cook for 12 minutes, shaking the basket halfway through.

After 12 minutes, add the mixed vegetables to the air fryer basket with the chicken. Cook for an additional 5-7 minutes, until chicken is cooked through and vegetables are tender.

Fluff the millet with a fork and serve on plates. Top with the air-fried chicken and vegetables.
