STIR FRIED PORK WITH POTATOES

A simple, homey yet delicious dish for lunch during MCO [Stay Home, Stay Safe].  I believe any novice cook can give this dish a try instead of 'tapau'.
The marinated pork cubes are tasty and blends well with the soft potato cubes.  The original recipe uses only potatoes and pork but I have added big onions, red and green chillies for some 'oomph'.  You can omit these ingredients if cooking for children at home.
