This casserole is even better the next day, that is if it even makes it overnight! ---you may omit the jalapeno pepper if desired, we like onions so I always use two and lots of fresh garlic, you can increase the green chiles to whatever amount you desire, and use as much shredded cheese and cooked chicken as desired, the amounts listed are only a guideline, this also works well with cooked turkey, prep time does not include cooking the chicken --- this is *very* good!
