Clean the cuttlefish and carefully detach the bladder containing the black, avoiding breaking it. Cut the cuttlefish into strips and after washing them, let them drain well in a colander.

Prepare a stir-fry with oil, garlic, parsley and chili pepper in a frying pan. When the garlic is golden brown, add the cuttlefish and bladders. Break up the bladders with a ladle while cooking to add flavor.

Add the tomato fillets and a pinch of salt, then simmer with the lid on.

Boil spaghetti in salted water and drain when al dente.

Pour some of the sauce into a soup bowl, add the spaghetti and mix well. Spread the remaining sauce over the top and garnish with a sprinkling of chopped parsley.
