7oz200 g beef (freeze them in freezer for about 15 minutes prior to cooking so you can thinly slice them)
1cupthinly slices onion
4ozenoki mushrooms
4ozchoy sumchinese cabbage
Seasonings
dash of salt
dash of sugar
2Tbspteriyaki sauce
Instructions
Cut beef into thin slices. Remove skin and cut onions into thin strips. Trim away the roots of enoki mushrooms. Rinse and drain
Heat some oil, stir-fry onions and enoki mushrooms briefly, add salt and sugar. Remove
Place a slice of beef flat, it helps if you have a pestle or use the flat side of a cleaver/knife, and lightly flatten it so it will be thinner. Place onions and enoki mushrooms on the meat, roll up
Heat some oil, pan-fry beef rolls until fragrant and golden in color. Remove
Blanch choy sum in boiling water, remove. Transfer to the plate and top with beef rolls
Drizzle teriyaki sauce on top and serve
Notes
if beef slices are not thin enough, the beef will "unroll" itself when being pan-fried. You can chill the beef in the freezer for 15 minutes prior to slicing. I found it easier to slice it thinly after that
