Cut a spring cabbage into large pieces. Cut a turnip into 8 wedges. Snap off the tough stem end and peel to remove the stem toward the top stem.
Add a pinch of salt to boiling water, then add the cabbage and snap peas. After 1 minute, add the turnip wedges to cook extra 10 second. Drain using a colander and let it cool down.
Add the sauce to the bowl of vegetables. Add the sesame seeds and toss to distribute evenly.
