This Spinach Frittata makes the perfect “Mini Meal” since it has lean protein (egg whites,) veggies (spinach) and lots of flavor. I made this last Sunday for brunch and put individual slices into containers so I could reheat them during the week. I love it for brunch or late breakfast. It saves in the refrig well for easy reheat on busy mornings, too. It is so tasty and good for you! Enjoy! Prep: 15 minutes.
