Step 1

Process the chilli, garlic and lemongrass in a food processor until very finely chopped. Squeeze the pork mince from the sausage casings, discarding the casings. Add the mince to the food processor with the lime juice, fish sauce, egg and breadcrumbs and pulse until just combined. Roll mixture into 24 meatballs.

Step 2

Heat the oil in a large frying pan over medium heat. Cook the meatballs in 2 batches, turning them often, for 5-7 mins or until cooked through. Remove from heat.

Step 3

Place 3 meatballs in each lettuce leaf. Top with carrot, cucumber, mint, basil and drizzle with sweet chilli sauce.
