Coleslaw is a simple thing, made with simple ingredients. The way Joanna Gaines makes it her own is by adding Brussels sprouts, celery and green onion to a standard rainbow shredded cabbage mix. Great news: It only takes 10 minutes to put together. In a large bowl, stir together the slaw, Brussels sprouts, celery, and green onions. In a small bowl, stir together the mayonnaise, vinegar, celery seeds, celery salt, paprika, and salt and pepper to taste.
