Combine bulgur wheat and water in a small saucepan and bring to a boil.
Reduce heat to low, cover, and simmer for 12 to 15 minutes or until water is fully absorbed.
Fluff the cooked bulgur with a fork and spread it on a baking sheet to cool to room temperature.
In a large mixing bowl, combine the cooled bulgur, diced cucumbers, red onion, parsley, mint, pistachios, chickpeas, and feta cheese.
In a small jar or bowl, whisk together the olive oil, lemon juice, salt, and pepper until emulsified.
Pour the dressing over the salad and toss thoroughly to ensure even distribution of ingredients.
Serve immediately or refrigerate for 30 minutes to allow the flavors to develop.
