I buy the big carton of egg whites. I started out just dumping the yokes a few years ago, but since I buy organic eggs now, that's way too wasteful and expensive. We manage to still go through quite a few eggs a week, even with me using the whites from a carton. Sometimes I mix the whites with regular eggs, sometimes I just eat regular eggs. But, since this is the only way I can up my protein at breakfast (I'm allergic to whey), it works.
