Lightly flatten the bread slices with a kitchen roll to make it thin.
Spread a thin layer of La Vache qui rit triangle portions on the loaf bread slice and top it with 1 lettuce leaf to make a base that will keep the bread dry.
Add a layer of tuna, 1 slice of La Vache qui rit triangle portions, and 5 carrot sticks.
Gently roll up the bread and shape it into a nice roll.
Using a knife, cut both ends of the bread rolls, then halve each one to get mini bread sushi rolls.
