Ingredients

• 500g beef sirloin or fillet 
 

• Marinade:

• generous grinds of freshly ground black pepper

• 1 1/2 teaspoons sugar
• 2 cloves garlic, finely chopped
• 1 tablespoon oyster sauce
• 1 tablespoon fish sauce
• 1 tablespoon soy sauce
• Dressing:
• 
1 spring onion, thinly sliced
• 1 1/2 teaspoon sugar
• salt and freshly ground black pepper
• 1 1/2 tablespoons rice vinegar

• 2 tablespoons water
• 1/3 cup roasted peanuts, roughly chopped
• watercress and steamed green beans to serve

Method

Trim excess fat from the beef and then cut into small chunks or slices.
.In a bowl, combine the pepper, sugar, garlic, oyster sauce, fish sauce and soy sauce. Add the beef and toss well to coat. Set aside to marinate for 20 minutes or up to 2 hours.

2. For the dressing, combine the spring onion, sugar, salt, pepper, vinegar and water. Stir to dissolve the sugar.

Heat a drizzle of oi in a wok or large frying pan over a high heat. Cook the beef in batches, allowing it to sear for about 1 minute, before shaking the wok or pan to sear another side. Cook for another 30 seconds or so and shake. Cook the beef this way for about 4 minutes total, until nicely browned but not overcooked.

4. Arrange the steamed beans and watercress on a platter, drizzle with dressing and top with beef.  Sprinkle with peanuts and serve with rice.
