To cook, choose which options works better for you:
Air Fryer: Preheat airfyer to 390 degrees F. Once preheated place chicken cubes in air fryer with space in between (you may need to do several rounds as you do not want to overcrowd the air fryer. Lightly spray with canola or olive oil to help them brown in air fryer. Set air fryer for 12 minutes. Halfway through (at 6 minute mark) pause cooking, to flip chicken over. Finish cooking. Ensure chicken is cooked through.
Note: Air fryer temps may be different depending on air fryer
Oven: Preheat oven to 420 degrees F. Place chicken on a baking tray. Lightly spray with canola or olive oil to help them brown in oven. Bake for 12-15 minutes or until golden brown and cooked through.
