(You need an oven with a grill or broiler (heat from above)

½ bunch parsley
½ bunch basil
Fresh mozzarella cheese, whole pieces (avail. at Sheikh Abdallah, but not always in stock)
1 small packet / 1 portion corn flakes
Olive oil or butter
Salt, pepper

Cut the tomatoes and the mozzarella in slices and set (alternating one slice tomato and one slice mozzarella) in a greased ovenproof tray or Pyrex pan.
Chop the parsley and the basil, mix them together with the cornflakes, and spread the mixture over the tomatoes. Season with salt and pepper and sprinkle sparsely with olive oil or with small pieces of cold butter, according to your taste.
Put the pan under the preheated grill in the oven for 5 minutes.
