Is there a more versatile food than the egg? You can use it to prepare any meal of the day, and it can be fancy or plain. Anything from a quick dinner of scrambled eggs to a fancy brunch with quiche to a quick and dirty fried egg (particularly yummy if you calorie-plurge and fry it in bacon fat after cooking a couple slices of bacon).
Eggs are definitely a staple food around here, and we usually eat omelets for dinner once a week or so. Recently, thanks to Everyday Food, I discovered a new favorite way to serve eggs for dinner: Baked Eggs in Tomato-Parmesan Sauce. We tried this for the first time a couple of weeks ago, and it will definitely be staying in my repertoire.
