what's the easiest+healthiest chicken cut option for air frying? Tips on seasoning?

I have a small rice cooker and am getting an air fryer today. I'm trying to eat better, because for a while now, all I eat is fast food.

I'm trying to find a "staple meal" that is easy to make and better nutritionally than what I keep eating.

My schedule is a bit insane, so I really need something ready to make that is healthy. I need to eat better so that my health doesn't continue to decline...
