Cook Wheat berry in simmering salted water for about 2 hours. (Will become tender, but still remain slightly chewy) (Alternatively can soak in cold water overnight, and reduce cooking time to 50 minutes) Drain.
While that’s cooking, dice all the vegetables.
Mix items for juice together.
In a large bowl, add wheatberry, all the veggies, and top with juice. Add seeds and raisins. Add olive oil at the end, just enough to moisten salad.
