Chicken Enchiladas

Sunday night's dinner was Chicken Enchiladas. I am a huge fan of this dish. One of my favorite places to get them is Charritos in Hoboken, New Jersey (sigh...I miss Hoboken). Unfortunately, my enchiladas were nowhere near as wonderful as they are in Frank Sinatra's hometown and I won't bother posting the recipe. I need to make a great recipe for the sauce and need recommendations on technique (mine fell apart).
