Super simple. Grate the carrot using a cheese grater (the large size). Slice the cabbage as thin as you can go (use a mandolin if you got it!). Small dice on the onion, place all of these in a bowl.
Whisk together the dressing ingredients. If you don't have honey sub in 1 tsp of sugar.
Toss the dressing into the slaw and you're good to go! Serve it immediately or let it soak for up to 24 hours. Enjoy!
