Step 1

Combine cucumbers, tomatoes, green beans, garlic, and chile in a large bowl. Finely chop ½ cup peanuts to the size of lentils and add to bowl.

Step 2

Whisk lime juice, brown sugar, and fish sauce in a small bowl until sugar is dissolved.

Step 3

Pour dressing over vegetables and toss with your hands, gently squeezing as you go, until well coated and vegetables have wilted slightly, about 30 seconds. Taste salad and season with more lime juice, brown sugar, or fish sauce if needed. Salad should be equal parts sour and salty, with sweet close behind.

Step 4

Transfer salad to a platter. Coarsely chop remaining ¼ cup peanuts and scatter over salad.
