Prepare the Cucumber by cutting it in half diagonally and then cut into bite-sized pieces.
In a large bowl, mix Korean Chili Paste, Korean chili flakes, sesame oil, ground sesame seeds, sugar, minced garlic, and salt.
Add in sliced onions and chopped cucumber. Massage for 2-3 minutes until cucumber is coated in the paste. Taste to see if you need any more additional seasoning.
