Bigoi (*) Laid in a sardine sauce

(*) Bigoi are a specific big spaghetti integral pasta
3 sardines that have been preserved with salt, stewed onion, olive oil
I wash the sardines and get them rid of their fishbones.  In a frying-pan I put in the olive oil, the smashed sardines, then I add the onions already stewed in a separated pan.  
Once the Bigoi have been cooked in boiling water (Bigoi are specific big spaghetti, whole-wheat pasta) all the ingredients are mixed up together moving the pan.

N.B. This dish may also be tasted at normal temperature.
