Thai-Inspired Cucumber Relish

1/2 cup of rice wine vinegar or white vinegar
2 tablespoons of sugar  (plus 1/4 cup if you are using white vinegar)
1/2 teaspoon of salt
1 English cucumber
1/2 of a small red onion (about 1/2 cup sliced)
4 small red chilies
1 tablespoon of roughly chopped cilantro leaves
1 tablespoon of finely chopped peanuts

In a small saucepan, stir together the vinegar, the sugar, and the salt over medium heat until combined. Remove from the heat and allow to cool.

Partially peel the cucumber, making long stripes of alternating green and white flesh.

Slice the cucumber paper-thin.

Mince the onion.

When the vinegar sauce is cool, add the cucumbers and the onion and stir.

Slice the chilies into rings (remove the seeds if desired).

Add the chili rings and the chopped cilantro to the cucumbers and stir.

Transfer to a nice serving bowl and garnish with the chopped peanuts.
