Step 1 Preheat oven to 180°C. Using a small sharp knife, cut a horizontal slit in the side of each chicken breast. Push 2 teaspoons tomatoes and 2 cheese pieces into each slit. Wrap each breast in a prosciutto slice. Spray with oil.

Step 2 Heat a large frying pan over a high heat. Cook chicken for 1-2 minutes each side or until golden. Transfer to a baking paper-lined tray. Bake for 8-10 minutes or until cooked through.

Step 3 Meanwhile, boil potatoes for 10-12 minutes or until tender. Drain well then return to saucepan. Mash until smooth. Stir in milk, corn and chives. Serve corn mash with sliced chicken breast and green beans.
