Preheat oven to 350°, Then prepare a 9 x 13 baking dish by coating it with a non stick cooking spray.
Add chicken, sour cream, salsa, black beans, green onions, corn, taco seasoning, black pepper, cream of chicken soup and half of the cheddar cheese in a large bowl. Mix until well combined.
Crush chips by hand and spread half of them on the bottom of the prepared baking dish. Then spread half of the chicken mixture over the crushed chips.
Repeat and top with remaining cheddar cheese.
Bake for 30 minutes, until bubbly and cheese is completely melted.
