In a saucepan, bring the water to a boil. Add the faro and simmer uncovered for 40 minutes or until the farro is slightly chewy. Drain and set aside to cool.
Prepare the dressing by combining the cider vinegar, apple juice, lemon juice, salt, pepper, and slowly whisk in the oil.
In a large bowl combine the farro, celery, parsley, apples, and walnuts and toss with the dressing.
Notes
Much of the fat in this recipe comes from using both olive oil and walnuts.
