1. Preheat the oven to 180C.
2. Take the peppers and rub with one tablespoon of olive oil and place on a small baking tray lined with foil. Bake them in the oven for about 15 minutes,turning from time to time until blistered and starting to colour. Remove from the oven and leave to cool to room temperature.
3. When cool enough to handle,halve the peppers lengthwise,remove the seeds and peel away the skin. It should come away easily. Take the clean flesh and cut into 1cm wide strips. As you slice the peppers,lie the strips on a serving platter all running the same direction.
4. In a bowl stir together the remaining three tablespoons extra virgin olive oil,vinegar,shallots,garlic and a pinch of sugar. Pour this dressing over the peppers. Sprinkle the capers over the peppers and leave to marinate at room temperature for an hour or so. Just before serving,strew the peppers with the picked parsley leaves and sprinkle with a pinch of sea salt. Serve immediately.
