Cut 2-3 inches off of the bottom stem of the broccoli (reference video)
Then cut the broccoli head into long florets.
Put water into a pot and bring up to a boil. Season the water with salt.
Blanche the broccoli for 20-30 seconds.
Then use your knife and cut the blanched florets into skinnier pieces.
Use a salad spinner (or your hands) to shake off (or squeeze out) the excess water.
Place the broccoli pieces into a mixing bowl. Then pour-in the listed ingredients under "broccoli seasoning". Give it a thorough mix with your hands.
Cut the spring onion and place into the broccoli salad. Give one final mix.
Serve and enjoy :)
