Pearl Couscous Salad

To make couscous: Heat 1 tablespoon olive oil in a skillet over medium heat. Cook and stir couscous in hot oil until toasted and fragrant, 3 to 4 minutes. Pour in water and bring to a boil; cover, reduce heat to medium-low, and simmer until couscous is tender, about 10 minutes. Drain and rinse couscous under cold water in a colander, then transfer to a large serving bowl. Stir in remaining 4 tablespoons olive oil until well coated.

Place lentils in a small pan and cover with water; bring to a boil. Reduce heat to medium-low and simmer until lentils are tender, 15 to 20 minutes. Drain and rinse lentils under cold water in a colander; add to couscous.

To make the salad: Add tomatoes, cucumber, red bell pepper, cranberries, raisins, red onion, chives, green onion, parsley, and sumac to couscous-lentil mixture.

To make the dressing: Whisk olive oil, lemon juice, honey, salt, and pepper in a small bowl until well combined.

Pour dressing over salad; stir until coated. Let chill in the refrigerator until flavors blend, 8 hours to overnight.
