You can either choose complete eggd or egg whites for your dish. Egg whites are lower calorically and only contain protein, but lack some of the nutrients offered by the yolk like omega 3s and good cholesterol.
Also aim for farm-fresh, pasture raised eggs, as they are the most humane and offer some nutritional bonuses. That being said they are pricier, so cage-free is okay, and if those are not options, standard eggs work too!
