STEP 3/5
When the onion becomes transparent, stir-fry a little bit of oyster sauce, soy sauce, pepper, and salt, and the garnish is complete +_+
When the meat is almost cooked, add a little butter and grill it over low heat to get a better taste of the meat.
Stir-fry oyster sauce mushrooms with a little butter at the end also makes the taste richer.
Choose butter according to your preference ^^
