Peel and cut your kohlrabi into 1/2-inch pieces.
Finely dice your onion and cut the tomatoes into 1/2-inch pieces.
Chop the stem end off of the hot peppers, and remove the seeds, then finely chop.
In a large serving bowl, add all prepped veggies and herbs.
Drizzle with the oil and lime juice and sprinkle in the zest. Season to your taste with sea salt and pepper, then toss gently to combine.
Cover refrigerate for an hour or two before serving.
Enjoy!
