Pennywise, this looks really good!
The reserved liquid and such is for the rice, and we aren't supposed to use the quick cooking kind (your hunch was right).
To make this SBD-friendly, I would make the brown rice separately, then just add it in with the beans and tomatoes later. Skip the step where you add the tomato juice and water...just drain the tomatoes and toss the liquid.
I'll have to try this...yum!
