You will not really find this salad in Vietnam. This is the salad I wished was in Vietnam after I ate a bad grilled banana dessert and decided I would probably never eat (or travel) again. SOmething fresh and living and low on the food poisoning possibility scale.
I love Vietnamese food (and Vietnam! And the Vietnamese! So much!). I love the large amounts of greens and herbs and general freshness. I love how light and clean it all tastes. There would likely be ground pork and lots of fish sauce in this if it was more authentically Vietnamese, but this salad is just inspired by what I love about Vietnamese food.
