Cut the fish into small chunks, that are about 3cm by 4cm. to do this, put your knife diagonally into the fish, pulling off the skin if there is any. Get one piece of fish. Using your hands, put the fish into the flour. Roll around several time until it is fully covered. Next, take the fish out and put it in the egg, once again covering fully. Take it out and put it in the breadcrumbs and cover. Put your fish onto the greased tray and do this with all your fish chunks.
