Place the bulgur wheat in a large bowl and pour the boiling water over it.
Cover and let it sit for about 15 minutes, or until the bulgur has absorbed the water and is tender.
Fluff the bulgur with a fork and let it cool to room temperature.
While the bulgur is cooling, finely chop the parsley and mint. Make sure they are finely chopped for the best texture.
Dice the tomatoes and cucumber (if using).
Finely chop the green onions.
In a large mixing bowl, combine the cooled bulgur, chopped parsley, chopped mint, diced tomatoes, diced cucumber (if using), and chopped green onions.
In a small bowl, whisk together the fresh lemon juice, extra virgin olive oil, salt, and black pepper.
Pour the dressing over the tabbouleh and toss to combine thoroughly.
Transfer the tabbouleh to a serving dish.
Enjoy your meal!
