Mix the cheeses and cut a slit into the side of each chicken breast and stuff them evenly. Wrap each stuffed chicken breast with 2 rashers of bacon, so that they hold the chicken together, but not over-tight. Season with black pepper.
Place the chicken on a baking tray and roast in the pre-heated oven for 25-30 minutes, until the chicken is cooked through.
I like to serve this with new potatoes and seasonal vegetables.
