Slice the red cabbage and apple into thin strips using a sharp knife or mandoline slicer.
Make the dressing: In a small bowl, whisk together vegan mayo, apple cider vinegar, maple syrup, Dijon mustard, and salt.
Toss the sliced cabbage and apple with the dressing in a salad bowl until evenly coated.
Optionally, chill for 30 minutes before serving.
Notes
Half a red cabbage typically gives you about 4 cups or 360g shredded cabbage. To prepare it for slicing, strip away the outermost leaves, cut into quarters, rinse, and then cut away the thick white root. Want to keep the dressing from getting watery over time? The only catch is that it takes a bit of extra time.Salt the cabbage after shredding to extract moisture. Let it sit in a bowl for 30–60 minutes, then discard any liquid collecting in the bowl. Rinse, dry and then continue to use the cabbage to make the slaw.
