When I make breakfast I use whole eggs(rare, I usually make oatmeal), when I eat out I get egg whites and from what I've read around here, people prefer egg whites for reasons I'm not going to get into. Now depending on the answer, this may be a stupid question but do supermarkets sell egg whites? How are they packaged? I don't want to be wasteful and throw out the yolk just to get the white but if I can purchase just this, I'd eat a lot more eggs for breakfast.
