A copycat version of a delicious slaw served on Houston's Ding's Crispy Chicken Sandwich. Perfect slaw for any sandwich or side.
In a medium bowl, whisk together mayonnaise, pickle relish, buttermilk, prepared horseradish, brown mustard, apple cider vinegar, granulated sugar, salt and pepper.
Add cabbages, kale, scallions and parsley and toss to combine. Taste and reseason, if needed. Cover and chill.
Note: You can make the dressing up to three days ahead and keep refrigerated. Toss to combine with cabbage, kale, scallions and parsley to keep that crisp bite.
