optional additions: black beans, additional sour cream, cilantro
Preheat oven to 400 degrees. In a bowl, mix chicken, all but 1/3 cup of the salsa, and sour cream. (*see note)
In a greased pie dish (*see note) lay one tortilla in the bottom of the dish. Add 1/2 of the chicken mixture and spread it out in a layer on top of the tortilla. Add the second tortilla, then remaining chicken mixture, then top with last tortilla.
On top of the last tortilla, spread the remaining 1/3 cup salsa verde over the top, then sprinkle the cheese over the top.
Bake uncovered for 15-20 minutes until cheese is bubbly and completely melted. Serve warm with additional sour cream if desired and sprinkle with chopped cilantro.
