Warm half the olive oil in a large frying pan for which you have a lid, then lay in the cabbage halves cut side down, and leave to fry until they begin to colour; if need be, cook the cabbage halves in batches.
In the same pan, saute the garlic, ginger, chilli, peppercorns, star anise and cinnamon for a couple of minutes, until fragrant, then pour in the vinegar, soy sauce and pineapple juice, and bring to a simmer.
1 red pepper, stalk, pith and seeds discarded, flesh cut into 2cm cubes.
1 yellow pepper, stalk, pith and seeds discarded, flesh cut into 2cm cubes.
Return the cabbage to the pan, season with sea salt and pepper, cover and transfer to the oven for 30 minutes, or until the cabbage is tender.
