Ooh what is the stuffing in your arepa? It looks yummy. :)
I had to google to see what chameleon bread was, and found this blog. This person said they made a beetroot sourdough, but it reads more like they were experimenting. Was your chameleon bread like this?

I make bread regularly. I have made it with pumpkin, yuca, carrot, whole wheat, banana...but never with beetroot...it would be great to try that..., @phoenixwren
