Cut meat into medium thin strips. Transfer to bowl. Season with sugar, oyster sauce, black pepper. Mix well. Add potato starch, mix well. Set aside.
Slice onion and bell peppers into 1/3 inch thick.
On high heat, put some oil into pan. Put onion and garlic in, cook for about 1 minute. Add meat. Stir fry well. You will have to use whichever convenient for you to separate the meat while stir frying it (I use chopsticks). The potato starch makes them stick together.
When meat is half cooked, add bell peppers. Cook for a minute. Make a well, pour the soy sauce in, wait till bubbling, mix everything well. Put the water in to release the potato starch from the meat and also scrape the bottom of the pan to release the starch that sticks to it. The starch, with the seasoning, will coat the veggies and make them taste better.
Transfer to serving plate. Serve with rice. Enjoy!
