Spinach, Bacon and Onion Mini Quiche

I have been quiche hungry lately, but tend to not have 2 hours in the morning to make breakfast (a quiche usually takes about an hour to bake, not to mention the time to prep filling and make the crust). So, the thought popped into my head to make a smaller version. I looked at the ingredients I had on hand, and these yummy little breakfast goodies were born!
4 slices turkey bacon
1 cup diced onion
2 cups fresh spinach, stems removed
1/4 tsp salt
1 tsp pepper
4 eggs
3/4 cup lowfat sour cream
1/2 cup milk
1 cup reduced fat shredded cheddar
1/4 cup parmesan cheese, grated
1 store bought or homemade pie crust (I halved my regular pie crust recipe and it made 10 muffin size quiches

Cook bacon in sautee pan. Allow to cool on a paper towel. In the same pan, add the onion and sautee until tender. Stir in the spinach until wilted. In a small bowl, beat together the eggs, milk and sour cream. Season with salt and pepper. Add the veggies, chopped bacon and all of the cheese. Stir until combined. Cut pie crust into 4 inch circles. Line muffin tins with circles (you should have about 10). Fill each crust with the filling. Bake in a 400 degree oven for 25 minutes, or until filling is set. Yield 10 muffin sized quiches
