That's another advantage of hard boiled eggs. You can feed the yolks to dogs or boys or even some cats. But I decided a long time ago that eating food that makes me overweight is even more wasteful than throwing it away. It took me a while to embrace that concept considering my "wasting food is a sin" upbringing by parents raised during the depression, but for me it was really important. I have also chosen not to scrimp on cost vs. diet.
