Preheat the oven to 375 degrees. Place a pie or quiche pan on a small baking sheet to make it easier to handle and to catch the drips. Lay the prepared pie crust into the quiche pan and trim the edges.
Layer the broccoli in the bottom of the prepared pan. Combine the cheese with the flour in a small dish and toss to coat. Sprinkle this over the broccoli. Sprinkle the bacon over the cheese.
In a large mixing bowl, combine the eggs and half and half. Season to taste with salt and pepper. Pour this mixture over the fillings in the pie shell. (This is the point at which you could freeze it, if making it in advance. Lay the pie plate on a rack in the freezer until firm. Wrap tightly with foil and place inside a labeled, ziptop freezer bag.)
Bake the quiche for 30 minutes or until set and golden. Allow to cool slightly before serving.
(If baking from frozen, there’s no need to thaw. Just add 5 to 10 minutes to your baking time.)
