If I recall…I think I saw that you were from Portland (like I am). New Seasons and Whole foods have organic raw buckwheat in bulk that you can purchase and get any amount you want. I stock up on it for every few weeks at a time! Get the raw stuff instead of cooked, same flavor but not cooked! I add some herbs to it and it comes out tasty.
Buckwheat will become on your greatest friends on the diet and it tastes pretty good. Great rice replacement. You can also get buckwheat flour which you can add to the coconut bread (read the recipe’s section for this one).
All of the bob’s red mill products are allowed including buckwheat; just as long as they are on the allowed foods list. Bob’s makes a great oat bran that I like also! This is also allowed.
