Trim the asparagus. Cut off the tough ends and/or peel them a bit. I'm personally too lazy to peel them, so I just trim them down. Cut them into 1 inch pieces. If you want to be fancy, cut them on the diagonal which somehow looks better. It doesn't take much more work.

Heat your frying pan up and put the sesame seeds in it. Stir them constantly until they are toasted. Remove them from the pan and set them aside.

Heat the oil in the pan. Add the asparagus and cook, stirring constantly, about 3 minutes. If you happen to have a green onion, add it at the same time. If not, skip it or add some dried onion flakes if you'd like.

Add the soy sauce, sesame oil, and sugar and stir. Cover and cook another 2-3 minutes, until the asparagus is tender. Sprinkle with the sesame seeds before serving.
