If using a frozen pie shell, remove it from the freezer. If you are making your own pie shell, do that now.
Preheat oven to 375 F.
Put all other ingredients into a bowl and whisk until fully combined.
Pour into pie shell and bake approximately 40 - 50 minutes until mostly set (just a bit jiggly in the center) and the crust is golden.
Cool completely, then chill.
Slice and enjoy!
