Cut aubergines into medium 5 cm pieces. Slice garlic, ginger, spring onions, and onion.
In a bowl, mix all marinade ingredients into the minced pork. Set aside for 10 minutes.
In a separate bowl, mix all the sauce ingredients until combined. Set aside.
Heat a large pan with a little oil over medium heat. Add ginger, garlic, and onion. Stir-fry for about 3 minutes until fragrant.
Add the marinated minced pork. Stir-fry for 4 minutes until lightly browned and cooked through.
Add the aubergines and pour in the prepared sauce. Stir well to combine.
Reduce heat to medium, cover with a lid, and braise gently for about 5 minutes until the aubergines are soft.
Remove the lid. Add two-thirds of the spring onions and chilli if using. Simmer uncovered for 1 to 2 minutes until the sauce reduces and glazes the aubergines.
Transfer to a serving dish and garnish with remaining spring onions and chilli. Serve hot with steamed jasmine rice.
