Mix the peanut butter, soy sauce and rice vinegar together and set aside.
Heat 2 tbsp of the vegetable oil in a large wok, then add the garlic and chilli. Stir fry on a high heat for 15-30 seconds until the garlic just starts to turn golden, then add the peppers and Tenderstem® broccoli. Stir fry, keeping the heat on high, for 4 minutes until just softened.
Rub the beef strips with the remaining vegetable oil. Move the vegetables to one side of the wok, then add the beef and let it sear on the other side of the wok for 15 seconds before mixing everything together to stir fry for a further 2 minutes.
After 2 minutes, the beef should be just cooked through. Lower the heat, then add the peanut sauce and ¾ of the sliced spring onions. Stir fry for a further minute, then divide between deep serving bowls. Top with the remaining spring onions and chopped peanuts and serve immediately with rice or noodles.
TOP TIP: Once you’ve sliced the spring onions, put them in a bowl of cold water – it’ll take away some of the sharpness, and crisp them up nicely
