Preheat your oven to 250C (480F). Place sausages in a roasting pan. Drizzle with a little olive oil.
Roast for 5 minutes. If you want to use whole cabbage now is the time to slice the cabbage as finely as you can be bothered but don’t worry about cracking out the mandoline (the finer you slice the quicker it will cook).
Sprinkle over vinegar. Toss, taste and season with more salt as needed. Serve mustard / mayo on the side.
