Chinese Hoppin' John
The Chinese use what is often referred to as black beans, but they're actually fermented soybeans.  

Azuki/Adzuki beans are the beans used in red bean paste. Most often, they're sweetened and mashed. But I don't see any reason you can't use them in Hoppin' John. I'd temper the slight sweetness of the azukis with a bit of black bean paste to give a more savory flavor. (The barbeque'd pork is already going to be a bit sweet.)
