This is a USA fire and Rescue's favorite recipes segment. To make this quiche you begin by preheating the oven to 350 degrees Fahrenheit. After that you combine cheese, and flour (the thickener) in a mixing bowl and toss them until the cheese is lightly coated. Next, add beaten egg, and pepper. Mix again. Now you need to add cooked and drained broccoli, and drained mushrooms. Mix again. Pour into a pie shell and cook for about an hour, or until it sets. A good tip is to cover the edges with tin foil about half way through the baking so the edges don't get too dark. The last minute of this video shows outtakes.
