Place the chicken breast on a board with a sheet of clingfilm on top. Cut the chicken fillet lengthwise, just above the top, fold it open and flatten it with a meat mallet or heavy pan, for example.
Cover the chicken breast with 2 slices of bacon, a layer of Boursin and some grated Parmesan cheese.
Wrap in cling film, roll up and leave to set in the fridge for an hour or overnight. Repeat with the other fillets.
Preheat the oven to 175 degrees Celsius / 350 Fahrenheit top and bottom heat.
Prepare 3 deep trays: 1 with flour mixed with plenty of salt and pepper, 1 with the (beaten) eggs and 1 with panko.
Dip the chicken in the flour, then the egg, then the panko.
Heat plenty of oil in a frying pan and fry the chicken cordon bleu on all sides until golden brown. It does not need to be cooked. Remove from the pan and place on a baking tray.
Bake in the oven for about 25-30 minutes. Serve with potatoes and green beans, enjoy!
