My First Stir Fry

1. Bring water to a boil and add 3 large Broccoli florets. After 3 minutes, add 1 thinly sliced Red (bell) pepper and blanch for 2 more minutes. Drain and set aside.
2. Crumble ⅓ low-salt beef stock cube into a jug and add 100ml / 3½fl oz boiling water. Add 1 level tsp Cornflour, 2 tbsp Low-salt soy sauce, 1 tsp Rice wine vinegar, and 1 tsp Sesame oil. Stir well and set aside.
3. Remove fat and gristle from 250g / 9oz Sirloin steak and cut into 1cm / ½in strips.
4. Heat a large frying pan or wok over high heat, add 1 tsp Stir-fry oil, and stir-fry steak with 2 finely grated Garlic cloves and 2cm / ¾in finely grated Ginger for 1-2 minutes until just undercooked. Remove from pan and set aside.
5. Add remaining oil to the pan and fry blanched vegetables for 3-4 minutes.
6. Add sauce and meat, cook for a couple of minutes until the sauce thickens and the beef is cooked through. Serve immediately.
