Sausage, Bacon, and Cararmelized Onion Quiche

Our Donuts for Dads breakfast was at church this morning.  I combined elements of a quiche recipe and a vidalia onion pie recipe to make this recipe that I am calling "Sausage, Bacon, and Caramelized Onion Quiche".  I made two of them, but the recipe that follows makes one quiche.

Sausage, Bacon, and Caramelized Onion Quiche
1 roll out refrigerated pie crust

1/2 lg. Vidalia onion, thinly sliced

4 Tbsp. unsalted butter

1/2 pack bacon, cut into lardons (very thin strips)

1/2 pkg. sausage

2 c. Cheddar cheese

3/4 c. Half and Half

6 eggs

1 tsp. salt

1 tsp. pepper

1 tsp. powdered mustard

Preheat oven to 450 degrees.  Crumble and cook the sausage; drain.  Fry bacon; drain.  Melt butter in a large fry pan and sauté onions until caramelized.  Place pie crust in 9-inch pie pan.  Make a thumbprint pattern with crust around the top of the pie plate.  Mix together cheese, sausage, bacon, and onions.  Sprinkle into pie crust.  In a large bowl, whisk together eggs, half and half, salt, pepper, and powdered mustard.  Pour over meats and onions.  Bake in 450 degree oven for 10 minutes.  Then decrease oven to 350 degrees and continue baking for 25-30 minutes until golden brown and set to touch.  

If top of crust starts to brown too much before quiche is done and set, make a tin foil ring and place over top edge of crust.
