In a large mixing bowl, combine the shredded purple cabbage, grated carrot, sliced red onion, and optional fresh cilantro or parsley.

In a separate smaller bowl, whisk together the mayonnaise, apple cider vinegar, honey or maple syrup, Dijon mustard, minced garlic, salt, and black pepper to make the zesty dressing.

Pour the zesty dressing over the cabbage mixture and toss until all the ingredients are well-coated.

Allow the slaw to marinate in the refrigerator for at least 30 minutes to allow the flavors to meld together.

Before serving, sprinkle the toasted sunflower seeds over the slaw for an extra crunch and nutty goodness.

Serve the Purple Cabbage Slaw as a refreshing side dish or as a topping for sandwiches, tacos, or grilled meats. Enjoy the vibrant colors and zesty flavors!
