Oil an oven tray. Lay several slices of either pancetta or prosciutto on the tray. Take one skinless chicken breast per person and carefully slice them to open them up flat. Lay the chicken pieces on top of the bacon slices. Put about two teaspoons of cheese on each breast and fold them back so that the cheese is inside. The cheese can be anything. Boursin is good as long as you don't overdo it. I tend to use tallegio meself but there are no rules. Wrap the bacon round the chicken as snugly aspossible. Put into hot oven, maybe 200 degrees, for 20 minutes. So easy!
