Heat the grill sauce in a clay cooking pot. Season the squid, sear them in the pot and set them aside.
Fry the bread slices in the same pot and save.
Using the same pot, lightly fry the finely chopped onion. When the onion begins to turn colour, add the tomato sauce and cook for 10 minutes over medium heat. Stir now and then.
Put the bread in a food processor with a couple of tablespoons of cooked beans, saffron and fish stock. The legumes will thicken the fish stock and make it more pleasing to the taste. Mix everything and add to the sauce.
When the sauce begins to boil, add the beans, squid, the chopped boiled eggs and chopped parsley. Let the stew simmer for 10 minutes and it’s ready to serve.
