- Bring a large pot of water to a boil. Toss in the spinach and blanch it for about 30 seconds to 1 minute, just until wilted. 
- Quickly drain the spinach and transfer it to a bowl of ice water to stop the cooking. Let it sit for 2 minutes, then drain again. 
- Squeeze out the excess water from the spinach and place it in a mixing bowl. 
- Add soy sauce, sesame oil, garlic, sesame seeds, and a pinch of salt. Use your hands or tongs to toss everything together until well coated. 
- Taste and adjust seasoning if needed. Serve chilled or at room temperature.
