Bring a large pot of salted water to boil and cook pasta according to package directions. Drain and set aside.
Preheat oven to 350º F and lightly grease a 9x13-inch baking dish with non-stick spray.
In a large bowl, combine chicken soup, nacho cheese, sour cream, chicken broth, fire-roasted tomatoes, green chiles, olives and 1 cup of the Mexican cheese, and stir until well-combined.
Add drained pasta and cooked chicken into nacho cheese mixture, toss together to combine, then transfer to greased baking dish.
Sprinkle remaining Mexican cheese blend over baking dish, then place in oven and bake for 30-35 minutes, or until cheese is melted and bubbly, and dish is heated through. Top with green onions and olives, serve, and enjoy!
