This recipe is a family favourite in my house. My Mum passed it down to me, and she got it from my Aunt. In New Zealand we tend to use "kūmara" which is a New Zealand variety of sweet potato, but your average "sweet potato" will work just as well. This salad is perfect on the side or on its own. A mixture of sweet, sour and crunch, this salad recipe is always a crowd pleaser, and is super simple.
