In a large bowl, combine the shredded kohlrabi, mint, Thai basil, cilantro, shallot, and chile.
In a small bowl or jar, whisk together the lime juice, fish sauce, brown sugar, ginger and garlic until well combined. Pour over the kohlrabi mixture, and toss to mix well.
Mix in ⅔ of the peanuts, then transfer salad and any juices in the bottom of the bowl to a serving plate. Top salad with remaining ⅓ of the peanuts and serve immediately.
