1 cup cucumber, sliced as thinly as possible into rounds
1/4 tsp. salt
1/2 cup (4 four-inch-long pieces) dried wakame
1 tbsp. rice vinegar
1 tbsp. water
1/2 tsp. sugar
1 tsp. soy sauce

Sprinkle cucumber slices with salt. When they soften, lightly squeeze the water out of them. Soak wakame 10 minutes in water to soften, and then cut into 1-inch lengths. Make dressing by mixing vinegar, water, sugar, and soy sauce. Stir cucumbers and wakame into dressing.
