Wok-tossed noodles seared over ferocious heat with spring onions, beansprouts, aromatic garlic, and savoury seasoned sauce.
Trim the watercress and slice the beef thinly.
Sear the beef in a hot pan with the oil until browned and just cooked.
Add the garlic, fish sauce, and sugar, and toss to glaze.
Pile the rice vermicelli in bowls, add the warm beef, then the watercress and pickled carrots and daikon.
Pour the nuoc cham over the bowl and serve with the watercress leaves still bright and crisp.
