Slice the aubergines and soak them in salted water for 10 minutes.
Mix soy sauce, oyster sauce, fish sauce, palm sugar, and water in a small bowl.
Heat vegetable oil in a wok over high heat, then add garlic and chilies.
Stir-fry the garlic and chilies for about 30 seconds until fragrant.
Drain and dry the aubergines, then add them, onions, and bell peppers to the wok.
Stir-fry for 5-7 minutes until the aubergines soften and the vegetables char slightly.
Pour the sauce mixture over the ingredients in the wok and stir well.
Reduce the heat to medium and simmer for 5 minutes until the aubergines are tender.
Add fresh basil leaves and stir-fry for another 1-2 minutes until the basil wilts.
