I like a good challenge. When I found this recipe on Pinterest boasting the entire loaf is only 500 calories, I knew I had to make it because even if I ate the entire thing, it was only 500 calories....only 500. Now, I do enjoy the full fat version of this very much. I make it every year, so I was curious to see how this tasted. It is certainly a yummy addition to my 3pm snack with my coffee and I only eat 1 serving at a time at 100 calories each. Delicious.
