Charred Cabbage with Buttermilk-Herb Dressing

Preheat grill to medium.

Cut cabbage in half through the core, leaving the core intact. Cut each half into quarters, trying to keep an equal portion of the core attached to each wedge--the core will help hold the wedges together on the grill. Brush both sides of cabbage wedges with oil.

Grill the cabbage until lightly charred on the outside and starting to soften, 6 to 8 minutes per side.

Meanwhile, whisk mayonnaise, buttermilk, vinegar, garlic powder, salt and pepper in a small bowl. Stir in herbs. Serve the cabbage drizzled with the dressing.
