My friend found this on another website and we both ended up making it. Excellent enchiladas! I added lots more cilantro and no chilis, to my taste. And I my chicken happened to have been marinated in a lime marinade, which I think gave it a good flavor. I may just add some lime next time.
Preheat oven to 375. Grease a 9x13-inch baking pan.
2
Saute onions in oil until just beginning to soften. Add shredded chicken, salt and mix to combine. Remove from heat and let cool.
3
Add cheese and toss. Set aside.
4
Soften the corn tortillas. The best way to do this is to lightly fry them for a few seconds in a hot skillet. Drain on a paper towel. You can also try wrapping them tightly in aluminum foil in the oven or wrapping them tightly in plastic wrap in the microwave.
5
Add the chicken mixture to each of 12 tortillas, rolling them and placing them seem-side down in the baking dish.
6
To create the sauce, melt the butter in a saucepan over medium heat. Add the flour and stir vigorously for a minute or so.
7
Whisk in chicken broth and cook until it thickens and bubbles.
8
Remove from heat and add sour cream and green chilies. Mix well.
