Place couscous in a large bowl and add boiling water or stock. Cover bowl with plastic wrap and let stand for 10 minutes.
Meanwhile, heat olive oil over medium heat and add onion; cook, stirring, until golden and soft. Add salt and cumin; stir to combine. Remove from heat and let cool slightly.
Uncover couscous and stir in herb paste, using a fork to fluff. Add onion mixture, pistachios, scallions, chile, and arugula; gently mix to combine. Serve at room temperature.
