In a pan brown the thinly sliced steak in hot oil. If you are using a REGULAR onion add now and brown with beef.
While beef is browning, in a separate bowl add water, corn starch, bouillon and white wine/oyster sauce/rice wine vinegar.
When Beef is just barely browned on both sides turn heat down and add soy sauce, ginger, brown sugar and your nice heaping spoonful of garlic. you can add two if you want.
Bring heat a back up and add your water mixture (haha, that sounds pleasant).
Stir till combined. bring to a bubbly simmer.
Now add broccoli and green onions (if you chose green).
Cook till broccoli is at desired tenderness. If sauce is a too thick for your liking mix in a couple tbps of water at a time till desired consistency.
Serve over your preferred rice. maybe with a side of won-tons?!
