Preparation
Boil the fish, drain with the help of a sieve and crush, taking care to remove all the spines. Cook the onion with a splash of water, and add the crushed soda biscuit and the skim milk. Turn off and add the cheese, nutmeg and fresh oregano. Next, add the fish and the beaten egg white. Integrate the ingredients very well and pour over a Pyrex mold barely impregnated with canola oil. Preheat the oven to 320 ° F and cook covered for 25 minutes, remove the foil and cook uncovered for another 5 minutes.
