Black pepper beef cubes

Overview

I saved some of the soy sauce beef I made yesterday and fried it in a different way.

Cut the beef in sauce into 1cm square pieces.
Clean the onions and green peppers and cut them into pieces about the same size as the beef.
Heat the pan, pour in oil, add onions and green peppers and stir-fry.
Sauté until the onions begin to turn transparent, add an appropriate amount of light soy sauce and stir-fry evenly.
Add beef cubes and stir-fry.
Finally, add a little salt and an appropriate amount of black pepper, stir well, and take it out of the pan and put it on a plate.
