Cook bacon and drain on paper towel.

Combine broccoli, red onion, grapes and celery in a large bowl.

In a seperate bowl, whisk together the mayonnaise, sugar and apple cider vinegar.

Crumble 6 slices of bacon and mix into broccoli mix. Add remaining 2 pieces to the dressing mix and whisk well.

Pour dressing over broccoli, add the slivered almonds and mix well until everything has been thoroughly coated.

Cover and refrigerate for at least 2 hours so that flavors can combine. Top with a pinch of slivered almonds.
