Leftover Roast Pork in a Sweet & Sour Barbecue Sauce

This dish started off with me following the chilli sauce recipe from Ching-He Huang's Chilli Chicken with Jasmine Rice, but as I added additional ingredients from a Thai Sweet & Sour dish I learnt in Thailand as I prefer the saltier flavours, it began to take on more of a barbecue sauce flavour.  The kids have devoured it, including mine and Dad's portions, so I had better write it down to be able to reproduce it again.

2 big handfuls of roast pork.  If you don't have this much you could always leave the pepper chunky and add a small tin of pineapple chunks to bulk the dish up.
1 tbsp sunflower oil

Sauce
1 tin of tomatoes
3 garlic cloves
2.5cm ginger
1 red pepper
2 tbsp light soy sauce
2 tbsp oyster sauce
2 tbsp sweet chilli sauce
2 tbsp tomato ketchup
1 tbsp sesame oil
1 tbsp lemon or lime juice
1 tsp sugar
1/2 teaspoon chilli flakes

Skin the garlic, de-seed and roughtly chop the pepper, roughtly chop the ginger and blend everything in a blender cup.

Fry the chopped pork in the sunflower oil, leaving it to brown as much as you dare.  Add the sauce and bring to the boil.  Serve with rice.
