Wash 1/2 cucumber thoroughly and slice thinly using a slicer.

Sprinkle 2 pinches of salt over the cucumber slices and mix well.

Prepare 2 imitation crab sticks and shred them into bite-sized pieces.

Let the salted cucumber sit for 10 minutes to draw out excess water.

Rinse the cucumber slices under running water to remove excess salt, then drain well.

Combine the cucumber and shredded imitation crab in a bowl. Add 1 tbsp oligosaccharide.

Add 1.5 tbsp vinegar to the mixture and mix thoroughly.
