"A wonderful brunch offering! This quiche is made without cheese and has a variety of mushrooms for added interest. Simply delicious, we are in love with this breakfast fare. This dish does take a while to make, but very much worth the work. High return on compliments and flavor! You may wish to add cheese, it's very good that way too."
