First off, you need to grate or finely shred/chop your carrots, cabbage and rutabaga. While this can very well be achieved with a box grater, you might want to take the heavy artillery out of the cupboard and use the grating disk of your food processor!
When all your veggies have been prepped, add them, along with the rest of the ingredients, to a large mixing bowl and mix with your hands (or a very large spoon) until very well combined.
You can serve this salad immediately or leave it in the refrigerator for a few hours to allow for flavors to fully develop.
This salad will keep very well in the refrigerator for up to 3-4 days.
