Preheat oven to 425°F (220°C).
Slice cabbage into wedges, making sure each wedge has part of the core to keep it together.
Whisk together remaining ingredients (except sausage) in a large bowl.
Gently toss cabbage wedges in the vinegar mixture to coat.
Arrange cabbage wedges in a single layer on a parchment lined baking sheet.
Place sausages on the same baking sheet.
Bake 20-30 minutes or until sausages reach an internal temperature of 170°F (77°C) and the cabbage turns golden on the edges.
