Heat the oil in a large non-stick frying pan with a lid. Tip in the onions and aubergine and fry for 8 minutes, stirring frequently, until soft and golden brown.
Tip in the pork and fry for 5 minutes, stirring occasionally, until it starts to brown. Mix in the pepper strips and stir fry for about 3 minutes until soft.
Sprinkle in the curry powder. Stir fry for a minute, then pour in the tomatoes and water. Stir vigorously, cover the pan and leave the mixture to simmer for 5 minutes until the tomatoes
break down to form a thick sauce (you can add a drop more water if the mixture gets too thick). Season with salt and pepper and serve with basmati rice.
