This is one of my favourite way of eating Japanese cucumbers.
How to make this: Cut cucumbers into bite size. Put into mixing bowl. Drizzle light soy sauce, a dash of sesame oil, a sprinkle of sugar, a big heapful of chilli broad bean sauce and drizzle with chilli oil. Let it chill in fridge for 30mins before serving.
Most of the time I do this by rough estimation, so this is the best direction I can provide. (^.^)
