If not using prepackaged shredded cabbage and carrot mix, you will have to finely shred about 6 cups of cabbage and 1 cup of carrots.
Mix the mayonnaise, sweetener, black pepper, cayenne pepper, apple cider vinegar, and salt together in a bowl.
Add the mixture to the shredded cabbage and carrots and mix thoroughly.
Refrigerate and serve chilled.
Notes
Each serving is only 5g net carbs. If you use my homemade spicy mayo, then you don't need to add extra cayenne pepper. But you might need to add some if you use store-bought mayonnaise.
