I was able to find a brown rice version in my local health food store, but they were overpriced and just not very good. (glutenfreeonashoestring.com)
I actually like cauliflower fried rice better than the actual rice version. (mindbodygreen.com)
Though nutritionally inferior, white rice flour can be substituted measure for measure should the brown rice version be difficult to find. (vegkitchen.com)
