Add chicken, apples, pecans, green onions, and cranberries to a large mixing bowl.
In a separate small mixing bowl mix together greek yogurt, mayonnaise, vinegar, maple syrup, rosemary, dijon mustard, and nutmeg. Season with salt and pepper to taste.
Pour over chicken mixture then toss to evenly coat.
Store in the fridge up to 2 days. Serve in lettuce or on whole grain bread.
Note that as mixture sits a few hours the chicken may absorb the dressing and it will seem to dry up a little. You can thin it with a little more Greek yogurt or mayonnaise, or water (depending on how creamy you want it).
