I'm a big fan of the crustless quiche for a variety of reasons. First, it's easy. Second, it works well for those who are gluten-free. Third, and this is true of all quiches, you can bake it once and eat on it for a few meals. Often, I'll prepare my quiche in 4-6 ceramic ramekins. You can buy a set with lids so that you've got some grab-and-go breakfast or lunch options for a few days.
