Boil the cuttlefish in a medium pot of water for about 10 minutes, or until fork tender.
Drain and cut into thin strips and toss into a large bowl.
For the celery: use a
vegetable peeler to create thin shavings. (To make the shavings crispier, chill them on a bed of ice for a few minutes.)
Add the
celery shavings to the bowl along with the
walnuts, freshly squeezed
lemon juice,
extra virgin olive oil, and salt. Mix well.
