Step 1

For the cabbage: Preheat the oven to 400 degrees F. Line 2 rimmed baking sheets with nonstick aluminum foil.

Step 2

Lay the cabbage slices flat on the baking sheets, two slices per sheet. In a small bowl, whisk together the olive oil, Dijon mustard, orange juice, honey, a pinch of salt and a few grinds of black pepper. Brush the mixture over the cabbage, then flip them and brush again.

Step 3

For the potatoes and sausage: Place the potato planks on the baking sheet with the cabbage, dividing them evenly between the two, and brush on both sides with olive oil. Sprinkle both sides with a dusting of garlic powder, onion powder, paprika, a pinch of salt and a few grinds of pepper.

Step 4

Add the bratwursts, two per baking sheet, and brush with oil. Roast, flipping everything halfway through, for 30 to 35 minutes.

Step 5

For the mustard sauce: In a small bowl, stir together the orange juice, Dijon mustard, parsley, honey, a pinch of salt and a few grinds of pepper.

Step 6

Chop the cabbage and transfer to a plate with the potatoes and bratwurst. Drizzle the mustard sauce over the top. Serve immediately.
