A break from the traditional creamy coleslaw with this tangy vegan version sweetened with apples, a perfect side dish or sandwich topping.
In a small saucepan over medium heat, combine the vinegar, sugar, mustard, celery seeds, and salt.
Bring to a boil, stirring until the sugar is dissolved.
Remove from the heat and add the oil.
Cool until just warm to the touch, about 30 minutes.
In a large bowl, jar, or zip-seal bag, combine the cabbage, onion, apple, and carrot; mix well.
Pour the warm dressing over the cabbage mixture.
Cover and marinate for 8 hours, refrigerated, or up to three days.
