Add cilantro and mint (optional) to taste.
Dress with the salad dressing and set aside to prepare the beef.
Heat a non-stick pan to medium high.
Add the oil, careful to use as little as possible so as not to make the meat topping too greasy.
Stir-fry the meat until browned and any residual moisture has been cooked off.
Add the onions and the garlic.
Cook until just translucent.
Add the oyster sauce and stir to distribute evenly.
Remove from flame.
Pour warm meat mixture over the prepared salad.
