01 - Preheat oven to 400°F. Line a rimmed baking sheet with parchment paper and set aside.
02 - Combine farro, water, and salt in a medium saucepan. Bring to a rolling boil over medium-high heat, then reduce to a gentle simmer. Cover and cook for 25 to 30 minutes until the grains are tender but still retain a slight chew. Drain any remaining liquid and spread the farro on a plate to cool to room temperature.
03 - Arrange the halved figs cut-side up on the prepared baking sheet. Drizzle with olive oil, then sprinkle with fresh thyme leaves, honey, and a pinch of salt. Roast for 15 to 18 minutes until the figs are caramelized and softened. Remove from the oven and let cool slightly.
04 - In a small bowl, whisk together the olive oil, balsamic vinegar, Dijon mustard, and honey until fully emulsified. Season with salt and freshly ground black pepper to taste.
05 - In a large serving bowl, combine the cooled farro, arugula, crumbled goat cheese, toasted walnuts, and sliced red onion. Drizzle the vinaigrette over the top and toss gently until all ingredients are evenly coated.
06 - Arrange the roasted figs over the top of the salad. Serve immediately at room temperature for the best flavor and texture.
