6 spring onions, trimmed and finely chopped (both green and white parts)
thumb-sized piece ginger, peeled and finely grated
½ -1 tsp chilli flakes
1 lime, zested and cut into wedges
1 tbsp sesame or sunflower oil
iceberg or Baby Gem lettuce leaves, to serve
4 sesame burger buns
25g roasted unsalted peanuts, roughly chopped
mayonnaise or sweet chilli sauce, to serve (optional)
In a large bowl, mix together the pork, oyster sauce, spring onions, ginger, chilli flakes and lime zest. Shape the mixture into 4 patties using your hands. Heat the oil in a large frying pan over a medium heat, add the patties and cook for 8 mins each side until cooked through.
To serve, put lettuce leaves on the bottom halves of the buns and squeeze over a little lime juice. Add the burgers, sprinkle over the peanuts and cover with the top halves of the buns. Serve with the remaining lime wedges and mayonnaise or sweet chilli sauce, if you like.
