Does anyone know anything about 'black foods', which include black beans, grains, rices, etc?

My colleague is Chinese / NZ and she gave me some to try the other day. This form is like a delicate porridge, I guess, and it has cocoa in it - so is all CHOCOLATELY ... :>

Anyway, it's supposed to be a sort of 'power food' combination. I have looked at the nutrition breakdown and it's low fat and not even ridiculous in carbs, and these 'whole' foods are supposed to be excellent in terms of nutrition / health.

Anyway, I just wondered if anyone has tried anything like this ... here is the funny / silly part: I have lost the bit of the packet that has an English translation on it ... so I don't know how to cook it (although I can work that bit out I am sure). I want to know more about what's in it and what makes it good, but obviously I can't read Chinese - LOL.

It is kinda a breakfasty thing ...

AND THE INTERNETS IS NOT HELPING AND GOOGLE IS NOT MY FRIEND TODAY!

Any advice / info appreciated ...
