Don't Waste That Egg Yolk

I always found it annoying when recipes call for egg whites or egg yolks only. I would throw out the other part of the egg. This time, when I used up the egg white and had a yolk left, I fried it scrambled style and served it to Niko. I have heard egg yolks are good for dog's coats.  Niko thought it was a good way to add some spice to his kibble.
