In a large salad bowl, whisk up the mayo, dijon, sugar, salt, pepper, and apple cider vinegar. Taste, and adjust any of the ingredients to your liking, like more Dijon or salt.
Toss the cabbage and sunflower seeds with the coleslaw dressing until well coated...and enjoy!
Notes
If using only cabbage, in a 3/4 cup serving size, this recipe is also Low FODMAP!!This coleslaw keeps well in the fridge for 3-4 days.
