Boil chicken until cooked through; drain and cool. When cool enough to handle, tear apart.
In large bowl combine chicken, both soups, and tomatoes; mix well.
Tear tortillas into fourths. In large baking pan layer tortillas, then chicken mixture and cheese. Repeat until chicken mixture and cheese are gone (best if top layer is cheese). Bake at 375°F until cheese is melted and hot.
Notes
Superb mexican dish that is always a family favourite.
