Ingredients

Sirloin steak, fat trimmed, sliced thin150 g
Weighed raw. The same piece weighed after cooking has lost water, so the protein per gram is higher and the total would come out about a quarter over.
Cooked rice noodles160 g
Cooked, rinsed cold and drained. Cooked weight, after soaking.
Cucumber80 g
Carrot50 g
Lettuce60 g
Peanuts, roasted unsalted10 g
Crushed over the top. They are 60 kcal, so measured rather than poured.
Fish sauceAbout 2 tsp (12 g)
Sugar1 tsp, about 4 g
Rapeseed oil5 g
Lime juiceJuice of a lime
Garlic2 cloves, about 6 g
Fresh red chilli1 red chilli, sliced
Fresh mintA handful

Method

Toss the beef with half the fish sauce, half the garlic and plenty of black pepper. Lemongrass, if you have a stalk, goes in here chopped fine.
Make the dressing: the rest of the fish sauce and garlic, the sugar, lime juice, chilli and two tablespoons of water, stirred until the sugar dissolves.
Fry the beef in the oil over a very high heat for about two minutes, in one layer, until the edges brown.
Put the noodles on the lettuce, cucumber and grated carrot, add the beef, pour over the dressing and top with mint and crushed peanuts.

Worth knowing

Nothing is cooked except the beef, and the noodles can be done a day ahead. The dressing has no oil in it, which is how a bowl this full stays at 551 kcal.
Lemongrass is not in the ingredient table so it is not counted. A stalk is about 5 kcal and worth finding.
