Peel, chop and par boil potatoes for about 6-7 mins. Drain and leave to cool, otherwise they go mushy later when you add them to the sauce. Cook onions gently in olive oil until soft. Coat the cod fillets in flour and shake off excess

Now add tomatoes to the onions and break them up with a spoon. On another pan, heat some more oil and brown the cod. Add potatoes to the tomato sauce and start to simmer

After a few mins, the cod should be browned, now add the fish to the sauce. Simmer on low for about 20 mins. Meanwhile, rub the bread with garlic, drizzle with olive oil and sprinkle with oregano. Pop under the grill for a min or two until lightly browned on both sides

After the 20 mins, add lots of fresh parsley. Serve in a bowl with the bread
