The vibrant colours of this dish are almost as enticing as its robust flavours. Although I usually serve it warm, it is also very good cold. Substitute oregano or basil for the parsley, if you like.
Preheat the oven to 200°C, 400°F, gas 6. Cut the peppers in half lengthways, brush with a little of the olive oil and season with salt and pepper. Bake for 1 hour
