This is an easy rice salad from Thailand known as 'Yam kao'. Left over cold rice is mixed with a variety of flavourings including lemongrass, lime leaves, coconut and watercress.
The dressing is the only thing we used in the recipe. My wife is from Thailand and she said it tasted just like the real thing. For the salad, you can use any assortment of vegetables and fruits, as long as there are good combinations of sweet, savory, soft and crunchy. And by the way it's Khao Yam, not Yam Khao, but thanks for the dressing, it's not typically for what ingredients you can find in Europe, but works great with the sauce. - 14 Feb 2015 (Review from Allrecipes Southeast Asia)
