In a medium bowl, stir together the sunflower oil, sesame oil, 1 tablespoon of the honey, and a generous pinch of sea salt. Add the cilantro, peanuts, and scallions. Stir well to combine. Set aside.
In a separate bowl, combine the cabbage, mung bean sprouts, broccoli or pea sprouts, and celery.
In another bowl, stir together the soy sauce, rice vinegar, and remaining 2 teaspoons of honey. Stir to combine, pour over the vegetables, and toss to coat. Add half the cilantro-peanut mixture, toss again, and transfer to a serving dish. Top with the remaining cilantro relish and a sprinkling of sesame seeds.
