To keep the broccoli tender but crunchy, steam or boil it briefly then immediately shock it in ice water, drain and dry. Shocking in ice water, also called an ice bath, stops the cooking process and keeps the broccoli crisp and bright green. The culinary technique is called blanching. Watch the timing on cooking the broccoli. It's done when you can just pierce it with the tip of a sharp paring knife. You want it crisp tender, not soft.
