Method

1. Preheat the oven to 200C/gas 6.

2. Season the chicken breasts with salt and pepper, then, using a sharp knife make an incision at the wide end of the fillet and twist the knife to make a pocket for the stuffing.

3. Stuff the basil and the cheese into the pockets and wrap 3 slices of bacon around each breast.

4. Heat some vegetable oil in a frying pan and fry the breasts for 3 minutes on each side until crisp and golden. Transfer to the oven and cook for 20 minutes.
