I use a slightly modified version of the Serious Eats recipe.

I skip the fresh chiles because I can never find them, I have added a little adobo sauce from a chile in adobo can and it add the same flavor if you're in a pinch.
I also just use boneless skinless thighs like 90% of the time. As you can see above, I precut the thighs and marinade everything for 2 hours. That saves a goodly amount of time as the marinade is the majority of the prep. It's a perfect gameday or event snack for that reason, you can just grate the cheese and slice the scallions and finish it inside of 10 minutes. Always broil 1 minute too long though. The cheese is best heavily browned. The one pictured was rushed.
