Step 1 Place beef in a glass dish. Combine the soy sauce, 1 tablespoon of the sweet chilli sauce, half of the fish sauce and 1 crushed garlic clove in a bowl. Drizzle it over the beef and turn the beef until it is well-coated. Cover the bowl with plastic wrap and refrigerate for 20 minutes.

Step 2 Place the noodles in a heatproof bowl. Cover with boiling water and set aside for 5 minutes. Drain. Add remaining ingredients and toss.

Step 3 Preheat a chargrill pan to medium-high heat. Spray the beef with oil. Cook to your liking (for a medium steak, cook for 2-3 minutes each side). Set meat aside for 5 minutes to rest.

Step 4 Thinly slice beef across the grain. Add to the prepared noodles, toss and serve.
