Prepare the dressing by placing the ingredients in a small bowl and stirring until thoroughly combined. Set aside.
Shred the beets, carrots and apple in a food processor (use the grating disc).
Transfer to a large bowl (without the juice that may have collected in your food processor bowl), add the sliced onion, chopped parsley and pour over the dressing.
Stir thoroughly, season to taste, scatter over the sunflower seeds and refrigerate your beet slaw for 30 minutes before serving (if possible).
Notes
I recommend preparing the ingredients just before assembling the salad (so they are fresh and crunchy).
I do not recommend grating the vegetables by hand. Use a food processor for a super crunchy.
Use a sweet, rather than sour apple variety.
Make it vegan by using maple syrup or agave syrup instead of honey.
Parsley can be replaced by dill or chives (or use a combination of herbs).
Pumpkin seeds make a good substitute for sunflower seeds.
Transfer the shredded beets, carrots and apple from the food processor into a bowl without the juice (which may have collected in the food processor).
Best served chilled within 2 hours. Refrigerate your beet slaw for 30 minutes before serving, if possible.
Serve with fish, chicken or turkey, sandwiches, wraps, burgers or potato patties.
