Step 1

Heat a large wok over high heat. Combine the beef with half the soy sauce, then stir-fry for 3-4 minutes until lightly charred. Transfer to a plate.

Step 2

Add noodles to the wok with remaining soy sauce and stir-fry for 1-2 minutes until lightly charred. Add oils and chopped spring onion, then stir-fry for a further minute. Add fish sauce, 2 tbs water and broccolini, then cook for a further 2-3 minutes until tender.

Step 3

Return the beef and any resting juices to the wok and toss to heat through. Serve with bean sprouts, sliced spring onion and sambal oelek.
