Heat the oven to 360F (180C). Place turkey fillet between 2 pieces of cling film. Beat the fillets with a rolling pin into thin slices of about ½ inch thick.
Remove the foil and brush each fillet with 1 tbsp. of the pesto. Roll them up and wrap each roll in 2 slices of bacon. If necessary, secure with a skewer. Heat the butter in a frying pan and fry the rolls for 2 min on high heat until browned.
Place the rolls in a baking dish and bake for about 15 minutes in the oven. Cut into slanted slices and serve the rest of the pesto on the side.
