Cook the Broccoli; add Onions last 5 minutes.
Add Margarine to hot Broccoli to melt. (I cook broccoli and onions in microwave by directions on package.)
Also, do the rice in microwave (directions on box).
Add the Soup, cooked Rice, and Cheese; stir together.
Bake in 350°F/177°C oven for half an hour.
