Step by step recipe:

1. 15 min.
   Wash and drain 1 lettuce.
   
   Separate leaves that you will prepare as "chiffonnade", and remove the central stalk.
   
   You should only keep the tender part of the leaves.
2. 2 min.
   Pile up leaves...
3. 2 min.
   ...and roll up to make a kind of cylinder.
4. 3 min.
   Cut the roll into thin slices, at the beginning it's a bit rough...
5. 10 min.
   ...then you'll get tidy slices, which give nice ribbons, and a pretty chiffonnade.
6. 
   Your chiffonnade is ready.
