01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Arrange fig halves cut side up on the prepared baking sheet. Drizzle with honey. Roast for 15–18 minutes until caramelized but still tender. Set aside to cool slightly.
03 - While the figs roast, bring 2 cups water and 1/2 teaspoon salt to a boil in a medium saucepan. Stir in the farro, reduce heat to low, cover, and simmer for 25–30 minutes until tender. Drain excess water and let cool slightly.
04 - In a small bowl, whisk together the extra-virgin olive oil, fresh orange juice, balsamic vinegar, Dijon mustard, sea salt, and black pepper until well emulsified.
05 - In a large bowl, combine the cooked farro, arugula, orange segments, roasted figs, sliced red onion, and toasted walnuts. Drizzle with the dressing and toss gently to coat evenly.
06 - Transfer the salad to a serving platter and top with crumbled feta cheese. Serve immediately or at room temperature.
