Yum! This is a simple, good for you, and great tasting, and versatisle banana bread. I subbed 1/2 cup of the flour for quinoa flour, and subbed the flax seed & water mixture for one egg. My avocado was not ripe, but my bananas couldn't wait for them to get ripe, so instead, I used peanut butter, which worked well. Who doesn't like peanut butter & banana? The bread rose nicely and had great texture, too. I'll definately keep this recipe on hand! Thanks for posting, Lisa!
