Heat the olive oil in a pan. Don't skimp on the oil because the aubergine soaks up a lot. Roast the aubergine quarters gently. Take them out of the pan and put them into a ovenproof dish.
Preheat the oven to 200 °C (or 400 °F).
Add all the other ingredients to the pan. If there is no oil left, add some more. Fry until the tomatoes are mushy.
Spread the tomato mix on top of the aubergine quarters.
Cover with aluminum foil. Put the dish in the oven for 30 minutes.
