Morning Flax Muffin.. lower fat version

In honor of reading "Eat more, weigh less", I tried to make a version of the morning flax muffin with egg whites instead of eggs.  This morning I used 2 whites, 1/4 cup of ground flax, and splenda to taste..(couple of  Tablespoons) and 1/2 teas baking powder.  It turned out great.. very puffy.    I could hardly tell the yolks were gone.    It might work fine with one egg white and some water.. I will try that tomorrow.
