1. Trim the stem off of your collard greens so it's flush with the leaf.
2. Blanch Your Collard Green Leaves (optional): Bring a large shallow pan with water to a slow boil. Add one leaf for 30-60 seconds then place the leaf in the ice bath for 10 seconds. Repeat for every leaf.
3. In a large bowl mix mayo, dried cranberries, chopped apples, pistachios, garlic, onion, salt and pepper in a large bowl.
4. Stack two leaves on top of each other, fill with ¼ of chicken mixture and roll them up. If you blanch them, they will stay together on their own. If you don't, you will need a band or toothpick. I usually just use rubber bands!
