Since I got an air fryer, it's the only way I will eat a hot dog (at least if I prepare it).
Preheat air fryer for a few minutes, put hot dogs in for about 5 minutes, shaking basket around about half way through. If feeling particularly fancy, I'll then put the hot dog in a bun and place back in air fryer for about 1-2 more minutes to toast the bun just a touch. Usually I just eat them on bread though.
They are seriously the best and easiest hot dogs I've ever made.
