These aren't original and they do actually use canned ingredients, but you can make it all from scratch if you're so inclined. I don't have an exact recipe, but here is what we do for these yummy enchiladas...
De-bone one rotisserie chicken from the store (we use Honey Jalapeno flavor)
Mix shredded chicken, one 8oz package of cream cheese and 1 small can of chopped Hatch green chiles over medium heat until cream cheese is melted and it all is well blended.
Pour half a can of green enchilada sauce of your choice in the bottle of a casserole pan. Spoon chicken mixture into the center of a (preferably homemade) tortilla. Roll up tortilla and place seam side down in casserole dish. Continue until all chicken mixture is used. Pour the remaining enchilada sauce over enchiladas and top with Cheddar or Mexican Blend Cheese. Bake in 400 degree oven for 20 minutes or until cheese is all melted!
Yummmmmmm!!!! We serve with Spanich Rice.
