Place bulgur wheat in a small heat-proof bowl and pour boiling water over it; cover and let stand for 10 to 15 minutes until tender and water is absorbed.
Fluff the bulgur with a fork and allow it to cool to room temperature.
In a large mixing bowl, combine the finely chopped parsley, mint, diced tomatoes, and green onions.
In a separate small bowl, whisk together the olive oil, lemon juice, orange juice, orange zest, salt, and pepper to create the dressing.
Add the cooled bulgur to the herb mixture and toss to combine.
Pour the dressing over the salad and toss thoroughly to ensure even coating.
Cover and refrigerate for at least 30 minutes before serving to allow flavors to meld.
