Step 1

Place pork mince, carrot, beans, onion, coriander and 1 tablespoon of the fish sauce in a bowl. Use your hands to mix until well combined. Divide into 12 portions. Use your hands to shape each into 2cm-thick, round 5cm patties.

Step 2

Heat oil in a large frying pan over medium-high heat. Add half the patties and cook for 3 minutes each side or until golden. Transfer to a plate, cover loosely with foil and set aside. Repeat with remaining patties.

Step 3

Meanwhile, place the chilli, lime juice, sugar, extra oil and remaining fish sauce in a small bowl. Stir to combine and set aside.

Step 4

Place lettuce leaves on serving plates. Top with patties and drizzle with a little of the lime mixture. Serve with the remaining lime mixture.
