Sigeumchi namul (Korean Spinach Side Dish)

I've been totally digging this Korean spinach side dish, sigeumchi namul. It is so simple to make and it's a good way to use up spinach.
I used about a pound of bagged spinach to make this batch, but you can use one bundle of spinach. I've made it both ways and it's good either way.
The first thing you have to do is wash the spinach and then bring a big pot of water to a boil. Add the spinach to the salted, boiling water. Cook for 30 seconds and then dump the spinach in a colander and place spinach in an ice bath to stop the cooking. Gently squeeze the water out. Cut spinach into smaller pieces and place in a bowl.
Finely mince two cloves of garlic and one green onion and add to the spinach. Add about 1-2 tablespoons  of soy sauce and about 1/2 tablespoon of Korean sesame oil. Mix it by hand or with a spoon and garnish with sesame seeds.
This will keep in the refrigerator for a couple days, so I make a big batch and keep it on hand to eat with my rice.
