In a medium size bowl, preferably a bowl that can be covered(like a pyrex), add the Mayo, Cane Sugar, ACV, Salt & Pepper. Mix well.
Add the Coleslaw Mix & Green Onions(if using) in to the bowl and mix well. Depending on the size of your bowl, it may be easier to add the coleslaw in batches then mix.
Cover; keep in the refrigerator until time to serve. Stir a couple times to make sure all of the veggies stay coated.
Notes
:: For the BEST results :: Let marinate in the refrigerator for at least 4 hours. You can make this the night before but in my opinion, it tastes fresher the day of.
