Brown sausage and bacon in skillet. Drain and crumble. Set aside.
In a mixing bowl, blend eggs, sour cream and steak seasoning together until creamy.
Fold in sausage, bacon, ham, and both cheeses to make filling. Mix well.
Roll out a refrigerated pie crust until it fits into a 12" cast iron skillet. Press into the bottom and up the sides. Use fork to press edges into side of skillet. Pierce bottom of crust in several places with fork.
Pour filling into unbaked pie crust.
Bake at 350 degrees for 40 to 45 minutes until quiche is set, but still a little wobbly in the middle.
Cool for at least 30 minutes before serving.
Notes
A 9 inch deep dish pie plate may be used instead of a cast iron skillet if desired. Be sure to pre bake the crust if using the pie plate.
Feel free to substitute another type of cheese, such as monterey jack, if you can't find the swiss blend.
Make this recipe KETO by omitting the crust and baking only the filling to make a crustless quiche!
Store leftover quiche in the refrigerator for up to 3 days.
