This is coleslaw at its simplest and best. No onions. No carrots. No peppers. No mayonnaise. Just cabbage and peppery barbecue sauce.
Finely chop the cabbage by hand or shred it on a mandoline or using the shredding disk of a food processor. Place the cabbage in a large bowl and stir in the Vinegar Sauce. Let stand for 10 minutes, then taste for seasoning, adding salt and/or more sauce as needed.
