Reader Julie Sun from New York City takes lentils beyond the soup bowl with this healthy dish, which is perfect to pack for lunch.
In a small saucepan, bring water to a boil. Add lentils, reduce to a simmer, and cover; cook until lentils are tender, about 30 minutes. Drain and rinse under cool water. Meanwhile, in a large bowl, whisk together red-wine vinegar, lemon juice, and honey. Whisk in olive oil. Stir in lentils, walnuts, grapes, celery, and thyme. Add feta. Season to taste with salt and pepper.
