Someone at work made this this week and it was incredible. So I had to go find a recipe that I could modify to Weight Watchers standards. And I found MASSIVE zucchinis at the Amish farm stand in town, so how could I pass it up?
The original recipe can be found here on allrecipes.com (and its awesome).
I found mine on here on cookinglight.com.
In my recipe, I substituted oil for applesauce and half the sugar for Splenda.
Final result: too dense/wet and way too many blueberries. This could be because I halved the recipe and used a 9" long loaf pan, rather than the 8". But was still very tasty.
Update: For an even better recipe, see my second attempt at baking this bread.
