1 tsp black pepper
1 tsp salt
Zest of 1 lime
2 ripe avocados
1 tomato, seeds scooped out, flesh chopped
Juice of 1/2 a lemon
1 green chilli, deseeded and chopped
1 Preheat the grill to medium-high.
2 Put the minced pork in a large bowl and add the black pepper, half a teaspoon of salt and the lime zest.
3 Mix to combine well. Use clean hands to form the mixture into eight equal, thin patties.
4 In another bowl, mash the avocados with the tomato, lime juice, chilli and remaining salt.
5 Dollop the avocado mixture on top of half of the patties, leaving room around the edges to seal the burgers without it leaking out.
6 Place the remaining patties on top and pinch the edges of the burgers together to seal all the way around.
7 Grill the burgers for 6-8 minutes per side until thoroughly cooked. Allow the burgers to rest for 10 minutes, then serve with crispy sweet potato chips.
