Extremely simple to make and explosively delicious. This is a Su-Mei Yu recipe. The ingredients can vary. I used one cucumber, some mint leaves, a minced birdseye chile, and a minced scallion. The dressing is made of fish sauce cooked down with sea salt, white sugar and palm sugar, then mixed with lime juice. Dried shrimp are put on top, and the whole thing sits for 10 minutes before eating.
