Notes
This recipe is super versatile.
I've doubled the chiles and cheese but kept the batter the same.
Doubled and tripled the recipe baking in a large casserole dish.
Used 2-3 (4 oz) cans of diced green chiles instead of whole chiles, poured them in the dish, with diced chunks of cheese or shredded cheese. Turned out great!
