We are usually not big fans of quiche, but we loved this one after tasting it at a friend's house. The flavors really blend well together. Note: This quiche is heavy on the spinach, that is how we like it, if you do not care as much for spinach and want more of an eggy filling, you may use less spinach. If you add an additional egg, the filling will overflow. I make this recipe a few times a month and find it fills a regular pie shell perfectly as written below.
