A friend shared this with me.  Take shredded hash brown potatoes and put
them in a greased pie pan.  Cook in oven until almost done (not browned,
but not crunch when tested with a fork).  Then add your quiche filling
recipe du jour.  Bake in oven until filling is cooked.  Edges of
potatoes and bottom will brown a little more.  Yummy.
