I've currently been eating black beans over rice almost every day! I just cook some black beans in my pressure cooker and when they're done I throw in a can of diced tomatoes, various spices, 1/2 an onion and cook it for a while. I also make the brown rice in a pressure cooker, it's very easy and comes out great. Very cheap too. I buy the rice and beans in bulk at my local co-op.
