I got this recipe from one of my Gooseberry Patch Cookbooks.  I will say that the taste was pretty good, but there are a few things I would change next time.
For one, I will use chicken tenders instead of the canned chicken, I'm not a big fan of the canned taste.  I also think that I will fry up the chicken tenders AND the onion before adding it to the rest of the ingredients. 
 
CHICKEN TEX MEX BAKE
 
2 12-1/2 oz. cans chicken, drained and shredded 
2 10 oz. cans mild red enchilada sauce 
10-3/4 oz. can cream of chicken soup 
4 oz. can diced green chiles 
14 1/2 oz. can diced tomatoes 
2 1/2 c. shredded Mexican blend cheese, divided 
1 c. sour cream
1/2 c. onion, diced 
1/2 t. pepper
10 flour tortillas, cut into 1-inch squares and divided 
1/2 c. sliced black olives 
 
Combine first 5 ingredients and half of the cheese;  mix well. 
 
 
Blend in sour cream, onion and pepper;  set aside. 
 
 
Arrange half the tortillas over the bottom of a 13"x9" baking pan sprayed with non-stick vegetable spray.  Spoon a layer of chicken mixture over tortillas. 
 
 
Repeat layering, ending with chicken mixture on top. Sprinkle with remaining cheese;  top with olives. 
 
 
Cover lightly with aluminum foil;  bake at 350 degrees for 40 minutes, or until hot and bubbly. 
 Serves 8.
