Method
Prep veggies: In a large bowl, toss shredded cabbage and carrot. Set aside.
Make dressing: In a small bowl, whisk together vegan mayonnaise, vinegar, oat milk, salt, and pepper until smooth.
Combine: Pour dressing over the shredded vegetables and toss to coat evenly.
Give a light final toss, garnish with chopped parsley and blueberries.
Rest or serve: You can serve immediately or refrigerate 15–60 minutes to let flavors meld. Taste and adjust salt/oiliness as needed.
Notes
The salad can be made a few hours ahead; keep chilled and add the herb sprinkle just before serving to keep herbs bright.
