Cut the aubergine and red pepper into little cubes. Chop the onion and garlic, halve the tomatoes.
Heat the oil in a pan, gently sauté the onion, then add the garlic, red pepper and aubergine. Put a lid on and sauté for 5 minutes. Add the spices and oregano, stir for a minute then add the tomatoes and a splash of water. Season with salt and pepper.
Put the lid back on, and cook for 15 minutes, or until the vegetables become tender.
Using a sharp knife, cut off the corn kernels or drain the tinned corn. Add the corn to the pan to heat through.
