Cut six piece of foil each about 10 inches square. Brush the shiny side of the foil squares lightly with oil and set aside until required.

With a sharp knife, slash each chicken breast at intervals, then slice the Mozzarella cheese and place between the cuts in the chicken.

Divide the courgettes (zucchini) and tomatoes between the pieces of foil and sprinkle with black pepper. Tear or roughly chop the basil or oregano and scatter over the vegetables in each parcel.

Place the chicken on top of each pile of vegetables then wrap in the foil to enclose the chicken and vegetables, tucking in the ends.

Place on a baking tray (cookie sheet) and bake in a preheated oven, 400F for about 30 minutes.

To serve, unwrap each foil parcel and serve with rice or pasta.
