- Trim any sinew or fat from the beef and discard. Slice beef as thinly as possible across the grain. Mix beef with lime zest, garlic, soy sauce and sesame oil.

Tip noodles and broccoli into a colander and cool under cold water, then drain well.

- Add drained noodles and broccoli to the frypan with the spring onion and sesame seeds. Toss over high heat to fully heat through (about 1-2 minutes), then stir in lime juice and pile into bowls or plates. Serve at once.
