Beef Strips, Cheesy Chips 'n' Posh Gravy

Meanwhile, halve, peel and thinly slice the red onion. Thinly slice the mushrooms. Trim the green beans.

Heat a drizzle of oil in a frying pan on high heat. Add the beef strips and season with salt and pepper. Stir-fry until nicely browned on the outside, 2 mins. IMPORTANT: Wash your hands after handling raw meat. Once browned, remove the meat to a bowl. Put your pan back on the heat and turn the heat to medium-high. Add the onion and mushrooms along with a drizzle of oil. Season with salt and pepper, then stir-fry until golden and soft, 5-6 mins.

When the mushrooms are browned, stir in the flour and cook for 1 minute. Add the beef strips back in, then pour in the water (see ingredients for amount) and add the red wine stock paste. Stir together and bring the mixture to a simmer. Simmer until the sauce is nice and glossy and slightly reduced, 10-15 mins. IMPORTANT: The beef is safe to eat when the outside is cooked.

Meanwhile, bring a medium saucepan of water to the boil with 1/2 tsp of salt. Add the beans to the water and simmer until tender, 4-6 mins. Once cooked, drain in a colander.
