I boiled my chicken, sauteed the onions with toasted long green anaheim chiles, which most stores roast ahead and sell by the bag fresh, no tomatoes, add fresh garlic, a tiny pinch of cumin (it goes a long way), salt. I take the green chile, you can use canned long green, put it in blender and puree. Instead of using raw tortillas, try using tostada chips, being sure not to use too much liquid in your crock pot. lot's of cheese. Now what do think? If you want the enchiladas to taste like real enchiladas, use red enchilada sauce, or the green if you like. You can also brown ground beef and make them red, use green with the chicken. I am from the border of Mexico and TX, so I like the real thing. I make all my own sauces. Very easy.
