Combine cleaned meat, egg, Dijon, parsley, red peppers, and breadcrumbs with a dash of Viking salt. Preheat the oven to 400°F (205°C). Remove skin and bottom belly of the fillet, then salt and pepper both sides. Place skin-side-up (for easier rolling) and fill with crab mixture. Roll the fillet with stuffing inside, tucking the ends underneath. Place in a pan and pour some Beurre Blanc over the fish and top with breadcrumbs. Place the pan in the oven on a low broil and check after 10 minutes. Meanwhile, warm up your Beurre Blanc sauce.
