1. Place the greens, shaved parsnip, carrot and apple, feta cheese and walnuts in a large salad bowl. Mix well.
2. In a separate medium sized bowl, whisk the olive oil, vinegar, mustard, honey and minced shallot to make the dressing.
3. Pour the dressing over the salad and mix well to combine. Garnish with the dried cranberries, if desired, and serve immediately.
4. Bake the walnuts for 15-20 minutes, tossing mid-way through, until crispy; watch closely so that they do not burn. Once out of the oven, they will continue to crisp and the honey will harden as they cool. Set aside.
