This is the ultimate French fast food - healthy and so appetising. Easy to make and great for lunches and picnics.
You can wrap them in cling film or foil and put in the fridge overnight and they will be ready for your lunch or picnic. They seem to improve if left this way as the bread becomes soaked with the olive oil which is how they should be. If you don't like anchovies you can use tuna instead or simply have a vegetarian version.
