Place pork in a freezeable container, then partially freeze the meat (this makes it easier to slice thinly).
Thinly slice into bite-size strips.
Stovetop method, meat step: heat a skillet over high temperature, then add the cooking oil and sesame oil; saute the sliced pork, stirring often, until no longer pink, about 2 minutes.
Microwave method, meat step: preheat a 6 1/2-inch microwave browning dish on 100% power for 4 minutes; add the cooking oil and sesame oil to browning dish and swirl to coat the dish; add the sliced pork and microwave, covered, on 100% power for 1 1/2 to 2 1/2 minutes or till pork is no longer pink, stirring every 30 seconds.

Note: I hope these instructions have been made clear for both methods! This was a recipe adoption, and I made changes to the instructions, hoping to make it a bit more understandable.
