Wash and peel cucumbers, then using a vegetable spiralizer or julienne peeler, peel cucumbers into strips stopping once you've reached the seeds, then place in a medium sized bowl.
In a small separate bowl add toasted sesame oil, rice vinegar, chili flakes, honey, and salt, then whisk until combined. Pour over cucumber strips and mix well. Top with chopped peanuts and sliced green onions.
Add extra chili flakes if desired. Best when served immediately.
