Thai salad of prawns and pink grapefruit on betel leaves

This fabulously tasty snack is based on one commonly sold by street vendors in Thailand known as ‘Miang Lao’. The original is a rather complicated affair including tiny dried shrimps and salted turnips. This version is simpler and more of a tangy, refreshing salad. The actual leaves on which the salad is served are known as ‘betel leaves’ and can sometimes be ordered from Asian greengrocers, but if you can’t find any use baby spinach leaves for an equally delicious alternative.
