Preheat the oven to 425℉/220℃.
Prepare the cabbage by removing any wilted outer leaves and slicing off the stem. Slice the cabbage in half lengthwise, then slice each half in half again for a total of four pieces. Slice those pieces in half lengthwise to yield eight pieces.
Brush 1 tablespoon of olive oil on a large baking sheet. Transfer the cabbage wedges to the sheet. In a small mixing bowl, combine 2 tablespoons of olive oil with the garlic powder, onion powder, and salt. Brush this mixture on top of each wedge, spreading any remaining mixture on the bottom sides.
Roast cabbage in the preheated oven for 15 minutes. Remove from oven and carefully flip each wedge. Sprinkle the wedges with the parmesan cheese.
Return the cabbage to the oven and bake for another 8 to 10 minutes until the cheese is slightly browned. Remove from oven.
In the meantime, whisk together the remaining 2 tablespoons of olive oil, lemon juice, Dijon mustard, and honey.
Transfer the wedges to plates or a serving platter. Drizzle with the mustard sauce, using a small amount at first then adding more as desired. Alternatively, you can cut up the roasted cabbage and toss it with the sauce to serve as a salad. Enjoy!
