If you use a premium cut of beef (eg., tenderloin, sirloin, top round or bottom round), cooking this stir fried dish should take no more than five minutes. With a preparation time of about ten minutes, dinner would be ready in 15 minutes flat.
If, however, you find premium beef cuts to be too pricey, there’s a trick for that. Pressure-cook the beef without cutting, chill, slice then stir fry as you would slices of a premium cut of beef.
A tip: If using precooked tougher cut of meat, make sure you chill it well before slicing so that the meat does not fall apart while being cut.
