I don't really care for brown rice. At all. I'd rather eat cardboard. It has better flavor to me.
I love sushi, and I was thinking about my loverly white rice on some nori when I got to thinking if you could use potatoes instead of rice for the sushi rice portion. What a novel Idea!
Alas, someone else has thought of it! http://www.idahopotato.com/recipes/id-688/
There are lots more recipes out there, none of them vegan, but all easily adaptable to McDougall. I'm going to have to give it a shot and report back. I'm sorry I didn't do all the dirty work then report back to everyone. I was just really excited about the idea!
