Kohlrabi Apple Slaw with Yogurt Dressing

I was first introduced to kohlrabi when I worked at a local state park the summer after my first year in college. A fellow co-worker, 65-year old Ben, grew much of his own produce and used to bring me sliced kohlrabi packed in cold water. It was so refreshing and crispy! Ever since then I have been enjoying it and finding new ways to prepare it. Use whole milk Greek yogurt or coconut milk yogurt. They both work great!
