Either boil or steam fresh green beans for 6-8 minutes. You want them to still be fairly crunchy.
In the mean time, in a small bowl combine the soy sauce, the sesame oil and a pinch of sugar (Note from Elizabeth: the actual recipe calls for 1 tsp sugar but I don’t like that much). Mince the garlic and brown it for about 30 seconds in a large frying pan. Add the green beans. Add the sauce. Mix it all together and let the green beans soften a bit. If you want the green beans softer, turn the burners off and cover the frying pan. Let it all sit for awhile.
Addition notes from my sister-in-law:
I also add crushed red pepper with the garlic. You can also add sesame seeds or more soy sauce/sesame oil.
In my opinion the green beans are best when they are still slightly crisp.
The whole recipe tastes best when it has been sitting for a few hours.
