We love Yakiniku beef.
On this dish are yakiniku beef strips (these are like bacon strips, only it was beef) marinated in light soy sauce and oyster sauce and pan-fried with a little olive oil. After frying, the oil from the beef strips came out and I used this to fry the eggs.
Here are two other ways I cook the beef strips: yakiniku beef with mushrooms and Yakiniku beef sandwich filling.
Greasy, definitely.
