01 - Rinse the barley under cold running water. In a medium saucepan, bring water and salt to a boil. Add barley, reduce heat, cover, and simmer for 30 minutes or until tender. Drain and let cool to room temperature.
02 - While the barley is cooking, segment the orange and grapefruit over a bowl to catch any juices. Set segments aside; reserve juice for the dressing.
03 - In a small bowl, whisk together the lemon juice, lime juice, citrus juice from the bowl, olive oil, honey (or maple syrup), white wine vinegar, lemon and lime zest, salt, and black pepper.
04 - In a large mixing bowl, combine cooled barley, citrus segments, red onion, parsley, and mint.
05 - Pour the dressing over the barley mixture and toss gently to combine. Taste and adjust seasoning as needed.
06 - Chill for at least 15 minutes before serving to allow flavors to meld. Serve cold or at room temperature.
