Preheat the oven: Preheat your oven to 400°F (200°C).
Prepare the cabbage: Remove the outer leaves from the cabbage and cut it into 8 equal wedges. Place the cabbage wedges on a baking sheet, brush them with olive oil, and season with salt and pepper.
Roast the cabbage: Roast the cabbage in the preheated oven for 25-30 minutes, or until the edges are crispy and golden brown. Make sure to flip them halfway through to ensure even cooking.
Prepare the vinaigrette: While the cabbage is roasting, whisk together the olive oil, balsamic vinegar, honey, minced garlic, salt, and pepper in a small bowl. Set the vinaigrette aside.
Assemble the salad: In a large serving platter, arrange the roasted cabbage wedges. Sprinkle the sliced red bell pepper, red onion, cilantro, feta cheese, and toasted sunflower seeds on top of the cabbage.
Drizzle with vinaigrette: Just before serving, drizzle the prepared vinaigrette over the salad. Ensure that each ingredient is nicely coated with the dressing.
Serve and enjoy: Serve your Roasted Cabbage Salad as a delicious and satisfying side dish or even as a light main course. The combination of the caramelized cabbage, fresh vegetables, and flavorful vinaigrette creates a symphony of tastes and textures that will surely impress your family and guests.
