I've replaced rice with mashed cauliflower... and it's my greatest find yet! I drown it in curry dishes, and it soaks up the yummies just like rice! I really recommend this.. and I've never been a fan of cauliflower before! As for gravy.. you can make your own and just omit the starches. It won't be as thick, but you'll at least enjoy the full flavor. As for milk.. I've been trying to figure that one out myself. I've been thinking of using heavy cream and diluting it with water, and shaking it up really good. I haven't tried it out yet... but it might be an idea for you to try.
