Mix the mashed potatos with the egg white (make sure that the potatos are cool, otherwise they will cook the egg bad. ) Heat a fry pan on high and you can either use a low fat cooking spray or water. Wait until water bubbles if you drop it in the pan. Then add your potato egg mixture it will bubble around the bottem edge just like regular pancakes. Flip it and watch for the bubble on the edge again.
You can top this with a fruit mix. I use 1/2 cup mixed berries crushed with 2 packets of splenda.
