This is one version of a quick quiche that could be easily changed to match whatever you have on hand.  I just used what I had in the freezer, which I thought tasted quite nicely together.

Sausage and Broccoli Quiche

9-inch pie crust
1 lb hot sausage
1/2 onion, diced
2 cups frozen broccoli florets, thawed and cut into bite-size pieces
1 cup sharp cheddar cheesse, shredded
3 eggs
3/4 cup milk
1/2 tsp mustard powder
1/4 tsp salt
1/4 tsp pepper

In a large skillet, cook sausage and onion, breaking up sausage as it cooks, over medium-high heat until sausage is fully cooked.  In a pie crust, spread the sausage/onion mixture and broccoli.  Sprinkle cheese on top.  In a bowl mix together eggs, milk, mustard powder, salt and pepper.  Pour this over the top and bake on 350 degrees until it is set and the top is golden brown, about 1 hour.
