Bring a pot of water to a good rolling boil on the stove.
Plop the chrysanthemum greens (whole) into the water, and boil for not more than a minute.
Drain as much excess water as possible out, then cut the greens into bite size or smaller pieces.
Plop drained greens in a small mixing bowl. Sprinkle the sesame seeds, soy sauce and sugar over the top, stir.
