Blanch the broccoli in a saucepan of boiling water for 1–2 minutes. Drain and set aside.
Spray a large nonstick wok or frying pan with cooking spray and heat over a high heat. Add the garlic, ginger and minced beef and stir-fry, breaking up the beef with a wooden spoon, for 3–4 minutes until the meat is browned.
Add the rice wine and char siu sauce and simmer for 1 minute. Add the broccoli and cook, stirring, for 1–2 minutes until heated through.
Remove the pan from the heat and scatter over the peanuts and chilli. Serve with rice noodles.
