I set up a little station with chicken broth in a sauce pan, cheese, minced onions, shreded chicken, green chilis and corn tortillas. rolling as I go and put in pan with enchilada suace topped with cheese.
For seasoning I use Cayenne, onion salt, pepper or a bit of fajita or taco seasoning in the chicken.
You can also layer like lasagna, but their harder to separate.
Good luck.
