Prepare the Dressing: In a medium-sized bowl, whisk together the mayonnaise, yellow mustard, apple cider vinegar, lemon juice, monk fruit sweetener, and celery salt. Mix well until the dressing is smooth and creamy.
Combine the Ingredients: In a large mixing bowl, add the coleslaw veggie mix. Pour the dressing over the cabbage mixture, ensuring that all the veggies are coated well.
Adjust Seasoning: Taste the coleslaw and add extra salt and pepper or more monk fruit sweetener as desired.
Chill or Serve: You can either chill the coleslaw in the refrigerator for about 30 minutes or serve it fresh right away. Either way, it's delicious!
