Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch baking dish.

In a medium bowl combine soup, chicken, sour cream, and green onions. Mix together. In another small bowl, combine salsa and green chile peppers; mix.

Cover the bottom of the baking dish with 4 tortillas. Add 1/2 of chicken mixture, 1/2 of salsa mixture, and 1 1/2 cups of shredded cheese. Repeat layers. Add another layer of remaining 4 tortillas and top with remaining cup of cheese.

Cover and bake in the preheated oven for 55 minutes. Uncover and bake for an additional 5 minutes, until cheese is melted on top. Let stand for 5 minutes before cutting.
