If using dried rice and lentils, cook the rice and lentils according to the package instructions. (It is best to slightly undercook rice and lentils so that they better absorb the vinaigrette.)
In a large bowl, combine the cooked rice and lentils with the cucumber, carrot, and herbs (if desired).
Directions for Vinaigrette: In a small bowl, whisk together the vinegar, oil, salt, honey and pepper. Pour over the salad and toss well.
