Add chicken broth and heat slowly, stirring occasionally until mixture comes to a light boil. Lightly heat tortillas in oil from chicken about 10 seconds each side, set on paper towels to drain. Take chicken out of refrigerator and cut up or shred. Taking a ladel of sauce pour some over the bottom of the 13x9 pan. Put 5 or 6 tortillas down, add some chicken, add some cheese and pour some sauce over this. Add another layer of tortillas and continue same process as before. Top layer should be sauce with cheese spread over top. Put in preheated 350 degree oven for about 30 minutes. Let set for 3 minutes before serving.
