Kale Slaw

1. In a medium bowl mix vinegar, onion, mustard, sugar, salt and black pepper. Add oil in a thin stream while constantly whisking until all oil has been incorporated.
2. Place kale and cabbage in large bowl. Add vinaigrette from step one.  Mix well.
3. Allow slaw to rest for 30 minutes to 1 hour. Slaw will start to wilt as it sits.
4. Using a slotted spoon, place wilted slaw in a serving bowl.  Discard extra dressing remaining in bowl (about 1/2 of the original dressing). Serve.

Notes:

• Add apples, raisins, dried cranberries, nuts or diced bell pepper for a extra flavor and crunch.
