01 - Preheat the oven to 400°F.
02 - In a medium saucepan, combine farro, water, and salt. Bring to a boil, reduce heat, and simmer uncovered for about 25–30 minutes, or until farro is tender. Drain any excess water and let cool to room temperature.
03 - While the farro cooks, toss the cherries with olive oil, balsamic vinegar, honey, and black pepper on a parchment-lined baking sheet. Roast for 15–18 minutes, until cherries are softened and slightly caramelized. Set aside to cool.
04 - Whisk together olive oil, balsamic vinegar, Dijon mustard, honey, sea salt, and pepper until emulsified.
05 - In a large bowl, combine cooked farro, roasted cherries (and their juices), arugula, red onion, walnuts, and half the feta. Drizzle with the dressing and toss gently to combine.
06 - Top salad with remaining feta before serving. Excellent served slightly warm or at room temperature.
