Put the liquid mix, lemongrass, garlic, red chilli, pepper and 2 tablespoons of cooking oil into a small food processor and process until smooth.
Pour into a bowl and add the thinly sliced steak. Mix thoroughly so the steak is well coated.
Bring a saucepan of well salted water to the boil. Add the rice sticks and boil until tender to the bite (about 7 mins).
While the noodles cook heat a wok or large frying pan over a high heat. Add the spring onion and cook for 2 minutes until slightly blistered. Remove and reserve in a bowl.
Next quickly fry tomatoes for 2 minutes until hot and collapsing. Remove and add to the spring onions.
Lastly fry off the beef and lemongrass mixture for 4-5 minutes or until the beef has coloured nicely all over. Add the sugar, mix well and stir fry for a minute further.
Add the beef mixture to the spring onions and tomatoes. Drain noodles and add to the bowl, toss well until combine.
Divide between plates. Top with bean sprouts, peanuts, fried shallots, lime and coriander.
