Rinse tofu with tap water and wrap with paper towel. Drain very well. I hold it in my hands and push. You don't need to worry about breaking it a bit. You will break it later as a process anyway.

Put cucumber, kimchi(I cut them into bite size with my scissors if they're bigger), tofu(break it with your hands) in your bowl.

Add apple cider vinegar, sesame oil and sesame seeds(optional) and mix well. Taste very depends on what kind of kimchi you use. Add whatever you want if you desire and explore!
