Preheat oven to 375. Spray a 9×9 inch baking dish with non-stick cooking spray.
In a medium bowl, mix chicken with the first 6 ingredients. in a separate small bowl, mix corn and black beans together.
Pour the chicken broth in a shallow bowl. Dip the tortillas in the chicken broth, just long enough to get them moist, (almost as you would dip bread in an egg mixture for french toast).
Layer 4 tortillas on the bottom of the prepared baking dish, followed by the chicken mixture, and ending with the corn and bean layer. Repeat the layers, ending with the tortilla layer.
Top with the shredded cheese, (and olives and green onions if desired). Bake for 25-30 min or until cheese is melted.
