Remove the crust from the bread slices and flatten them with a rolling pin, as you would with pastry, until each slice is 3 mm thick. Using a tablespoon, apply a very thin layer of pesto. Place the slices of smoked duck on top, then add a little pesto. Delicately make into a roll. Then cut the rolls into 6 portions.
Chop the rest of the pine nuts, fry them in the pan and sprinkle them on top of the rolls.
You can replace the pine nuts with fresh basil or crushed walnuts. This recipe can also be made with cured ham and string cheese.
