Beef stir-fry

• ½ red onion, thinly sliced
• sunflower oil, for cooking
• 400 g (14 oz)

Put the onion and some sunflower oil in a frying pan over high heat. Using a wooden spoon, sauté the onion for no more than 1 minute.

Add the steak to the pan and use the wooden spoon to move it around as you sear the meat for 1–2 minutes. The exterior of the meat should turn a brown colour but not necessarily be cooked.

Turn the heat down to medium.

Add the stock powder
