Wash the cucumbers under cool running water. Peel if the skin is hard, then cut in half lengthwise, scoop out seeds, and slice into thin half-moons. Set aside.

Rinse radishes to remove dirt, trim tops and bottoms, then slice paper-thin. Add to the bowl with cucumbers.

Chop scallions under running water and combine them with the cucumber and radish slices in the bowl.

Add cottage cheese to the bowl and season with sea salt and black pepper. Mix gently.

Carefully mix all the ingredients until evenly coated. Serve immediately or chill before serving.
