In a large bowl, dump in 2 (14 ounce) bags coleslaw mix. Note: I tend to like my slaw more finely chopped so I'll run the cole slaw mix in my food processor (using the pulse setting two or three times.)
In a smaller bowl, combine 1/3 cup white sugar, ¼ cup milk, ½ cup mayonnaise, ¼ cup buttermilk, 1 teaspoon Dijon mustard, 1 ½ Tablespoons apple cider vinegar, 1 ½ Tablespoons lemon juice, 2 Tablespoons freshly grated onion, ½ teaspoon salt and 1 teaspoon freshly ground black pepper. Whisk vigorously until thoroughly combined.
Pour mixture over coleslaw mix. Stir well to combine. Cover and allow mixture to sit in the refrigerator for about an hour before serving, if possible.
Stir again before serving.
