01 - Rinse farro thoroughly under cold running water. Combine farro, 3 cups water, and 1/2 teaspoon salt in a medium saucepan. Bring to a rolling boil over high heat, then reduce to a gentle simmer. Cook uncovered for 25 to 30 minutes until grains are tender yet still retain a slight chew. Drain through a colander and spread on a sheet pan to cool to room temperature.
02 - Halve the cherry tomatoes, thinly slice the red onion, and dice the cucumber. Roughly chop the parsley, mint, and basil. If using chives, slice them finely. Set all prepared produce aside.
03 - In a small bowl, combine the lemon zest, orange zest, lemon juice, orange juice, extra-virgin olive oil, honey or maple syrup, and minced garlic. Whisk vigorously until the dressing is emulsified and well blended. Season with salt and freshly ground black pepper to taste.
04 - Transfer the cooled farro to a large mixing bowl. Add the prepared cherry tomatoes, red onion, cucumber, parsley, mint, basil, and chives if using. Toss gently to distribute the ingredients evenly.
05 - Pour the citrus dressing over the salad and toss gently until all ingredients are evenly coated. If desired, scatter crumbled feta cheese and toasted pine nuts over the top.
06 - Serve immediately at room temperature, or cover and refrigerate for 30 minutes to allow the flavors to develop and meld together.
