Preheat oven to 375 degrees F.
Unroll pie crust and press into a 9 pie plate,
crimping the top edges if desired.
In a large bowl, whisk together eggs, milk,
salt and pepper.
Sprinkle ham, 1 cup of cheese, and green onions
into the pie crust and pour the egg mixture
over top. Sprinkle remaining 1/2 cup cheese on
top of egg mixture.
Bake for 35-40 minutes until the center is
completely set. Let cool for 5-10 minutes
before slicing and serving.
