Heat the oil in a room frying pan or wok on medium high heat.
Add the ginger and garlic and sauté for 30 seconds, don't worry if they brown slightly.
Add the beef slices, mixing it all up thoroughly to coat.
Add all the sauces and vinegar and again mix thoroughly, moving the beef around constantly. We are only going to cook the beef for about 2 minutes here.
Add the broccoli, pepper and water, continue mixing and frying for another 1-2 minutes. Don't overcook the broccoli, it still wants to remain a vibrant green.
Garnish as desired and serve with rice or with a bowl of noodles.
