Heat oven to 350 degrees F. Transfer refrigerated crust to a 9 inch glass deep-dish pie pan.
In a medium bowl whisk, beat eggs until blended, add half-and-half mix till blended. Stir in chicken, chips, both cheeses, 1 cup salsa, green chilies and salt. Pour into pie crust. Sprinkle all over with pepper (optional).
Bake 55-65 minutes or until crust is light golden brown and knife inserted in center comes out clean. Let stand for 10 minutes before serving.
