Mix minced garlic, green onion, soy sauce and sesame oil in a large bowl.
In a medium pot of boiling water, add 1 teaspoon of salt and blanch a bunch of spinach for 30 seconds. Drain the cooked spinach and rinse it in cold water 3 times, and squeeze it gently to get the water out.
Cut the spinach a few times and place the spinach into the sauce bowl and mix by hand.
Transfer the spinach onto a serving plate and sprinkle toasted sesame seeds.
