Bring water to a boil in a saucepan. Add couscous and reduce heat to simmer. Cover and cook until tender, about 15 minutes. Drain off any remaining water.
In a serving bowl, toss together couscous, arugula, cucumber, feta and eggs.
In a small bowl, whisk together lemon juice, olive oil, honey, basil, salt and pepper. Drizzle over salad and toss to combine.
