Lay kale leaves on a flat surface, sparsely drizzle with olive oil, then massage the kale leaves for one minute. Chop the kale leaves finely. In a large bowl, mix prepared kale and red cabbage. In smaller bowl, whisk together a dressing of shallot, apple cider vinegar, champagne vinegar, mayonnaise, and olive oil. Season with salt and pepper to taste. Add dressing to kale and cabbage mixture, tossing to coat evenly. Add in dried fruit pieces if desired, toss. Serve immediately or refrigerate until ready to serve.
