In a food processor, combine cod and the shrimp with the Italian Blend or substitute spices and pulse until it forms a sticky mass with some chunks of fish and shrimp. There should be no pieces larger than a half an inch. Transfer the fish and shrimp mixture to a bowl and add salt, pepper, mayonnaise, bread crumbs, flour, green onion and mix thoroughly until all is incorporated. Cover and let sit in fridge for about a half hour.
