In a medium saucepan, heat a touch of olive oil over medium heat. Add the couscous and toast, stirring frequently, until golden, 4 to 5 minutes.
Add 1¼ cups (300 ml) of water and ¼ teaspoon of the salt. Increase the heat and bring to a boil. Reduce the heat and simmer, covered, until the liquid is absorbed and the couscous is just tender, 9 to 10 minutes.
Set aside to cool slightly, but don’t let it sit too long before dressing, as it will start to get clumpy.
Meanwhile, in a small bowl, combine the preserved lemon peel, the 3 tablespoons olive oil, and the lemon juice. Season with ½ teaspoon salt and the Aleppo pepper.
Transfer the cooked couscous to a serving bowl. Add the chickpeas, bell pepper, cilantro, parsley, mint, pistachios, and apricots.
Drizzle with the lemon dressing and toss to combine. Season with salt to taste and an additional pinch or two of Aleppo pepper, if desired.
Serve warm or at room temperature.
