Preheat the oven to 220°C/gas mark 7. Season the chicken breasts and wrap 2 slices of Parma ham around each one. Place in a lightly oiled non-stick roasting tin and arrange the tomatoes around the chicken. Roast for 15-20 minutes until the chicken is cooked through.
Meanwhile, heat the olive oil in a large sauté pan. Add the onion and chopped rosemary leaves and cook gently for 8-10 minutes until softened. Stir in the courgette and cook for a further 5 minutes. Add the lentils, balsamic vinegar and blanched cabbage leaves, then cook for 5 minutes, stirring occasionally. Season to taste.
Divide the lentil and cabbage mixture among 4 plates. Slice the chicken and serve on top of the lentils with the roasted cherry tomatoes.
