Ok I love enchiladas they seriously are one of my favorite food I think what makes them so amazing is the sauce. Well when you are married to a wonderful man like mine who suffers from "I can't hardly eat any kind of food" you are forced to make substitutions. I will tell you right now this casserole is one of my favorite substitutions ever! My mother tried it and kept saying how she did not miss the tortillas at all. I am telling you as long as you have that unforgettable sauce you are golden! This casserole is also so great because it is protein packed with vegetables and no sugar! The other great thing about this recipe is that it can easily be turned into a vegetarian dish by substituting the chicken for butternut squash. Yes, you read that right butternut squash.
