What Brachah do you make on this crust?

Wow! I just went gluten-free because of my nursing baby - and it is so very hard to find what to eat! Ready-made gluten-free products cost a fortune, so finding this recipe is really exciting for me! And the best part about this recipe is that I finally have a use for that kilo of quinoa sitting in my freezer (my family did not take well to my attempts at feeding them quinoa:()! My question is just what bracha to make on it - is it hadama or shehakol?
