Make the dressing by mixing all salad dressing ingredients together in a bowl.
Taste-test for sourness/spiciness, adding more sugar if it's too sour for your taste or more chili if it's not spicy enough. Set aside.
Slice the cucumber, then cut the slices in half. Place in a salad bowl.
Add the grated carrot, cashews, red pepper, and spring onions.
Pour the dressing over and toss well.
Place herbs on a serving dish and spoon salad over. Serve immediately.
