Preheat the oven to 350°F (175°C).
In a mixing bowl, combine the shredded chicken, Buffalo sauce, black beans, corn, and half of the cheese. Stir until well mixed.
Spread a layer of enchilada sauce at the bottom of a large baking dish.
Layer half of the tortilla strips over the sauce.
Spread half of the chicken mixture on top of the tortilla strips.
Add another layer of tortilla strips and repeat the process: add the remaining chicken mixture, finish with a layer of enchilada sauce, and top it off with the remaining cheese.
Bake in the preheated oven for 25-30 minutes or until the cheese is melted and bubbly.
Garnish with chopped green onions before serving and enjoy!
