In a large mixing bowl, combine fresh broccoli florets, finely chopped red onion, raisins, sunflower seeds, and crumbled bacon.

In a separate bowl, whisk together mayonnaise, apple cider vinegar, and granulated sugar until well blended.

Pour the dressing over the broccoli mixture, tossing until all ingredients are evenly coated.

Season the broccoli salad with salt and black pepper to taste, adjusting as needed.

Refrigerate the salad for at least 1 hour before serving to allow the flavors to meld.

Before serving, give the broccoli salad a gentle toss to redistribute the dressing.

Serve this refreshing and crunchy Broccoli Salad as a delightful side dish, enjoying the combination of textures and flavors in every bite.
