Place a piece of plastic wrap on your worktop, place one chicken breast on it, season with salt and pepper, put on top of it 3 slices of cheddar cheese, 3 slices of bacon and wrap it in a roll like a caramel with the membrane so that it closes well.

Place a pan over high heat and let it heat. Once heated, remove the plastic wrap and sauté the roll for 2 minutes on each side, so that it gets a brown color. Follow the same procedure for the other chicken breast.

Place the puff pastry sheet on your worktop, after you have sprinkled a little flour on it, roll it out a little with a rolling pin and cut it in half.

With a brush spread 2 tablespoons of mustard on the surface of one roll, place on half of the sheet of puff pastry, wrap it well and with a fork and pierce the puff pastry on its outer surface. Follow the same procedure for the other chicken roll.
