Preheat the oven to 350 degrees. Spray a deep dish 9-inch pie pan with cooking spray.

Put the tortilla chips in a food storage bag and crush with a rolling pin until fine crumbs. You should have 3 cups crushed chips. Combine with the melted butter and press the mixture firmly into the bottom and up the sides of the prepared pie pan. Bake for 10 minutes. Leave the oven on.

Whisk the eggs with the cream, salt, and pepper. Add the salsa and cheese and stir well. Pour into the pie crust, place on a baking sheet and bake for 40-45 minutes or until the center is set. Let cool for a few minutes before serving.

Serve with sour cream, extra salsa, and cilantro if desired.
