This started its life as a recipe for a beef and noodle salad—served cold, but because of missing ingredients and my general forgetfulness, I arrived at this dish. It was gobbled up by all present—even the very fussy 96-year-old. I've posted the recipe here because the guests who ate it want to recreate it. It's tasty and fast to make—and not too spicy. It's also versatile. You can double or triple it, and you can leave out ingredients, add extra ones and even switch from beef to chicken. Oyster sauce is sweet, so be careful about adding the brown sugar, too.
