Preheat oven to 425 degrees. Place cod in a lightly-greased, shallow baking dish. In a small bowl, mix the Greek yogurt, chives, horseradish, lemon zest, and juice. Season mixture with sea salt and pepper. Cover cod evenly with mixture and top with cashews. Bake for 18-20 minutes or until the fish is done, and the crust is golden and crunchy.
