Giving three stars because it is a good, solid recipe. It didn't blow us over but we'd make it again. After making it as written, I added more chopped walnuts and about 1 tsp. more of maple syrup. The sherry vinegar was the most predominant flavor at first, and it was a bit strong. Additional maple syrup helped tone it down and the walnuts were just to add more nuttiness. Also would've added more kale. Maybe a cup more. Even if you have pre-chopped kale, I'd recommend chopping it more. Definitely a good recipe for farro.
Delicious side dish. Loved the nutty flavor of the farro in tandem with the walnuts.
