Bring a little Greece to your breakfast table with this crustless quiche. The tangy flavor of the feta is a tried-and-true sidekick of the fruity yet briny flavor of the Kalamata olive. Taste aside, six of these little drupes contain as much fiber as an orange, which is perfect if you are on a gluten-free diet trying to compensate for the fiber you had to give up with whole-wheat breads.
