Cover the bottom and the walls of the tray (or cake form) with baking paper. With a brush or a piece of napkin, smear it with a few drops of oil. Heat the oven to 180 degrees Celsius.
In a bowl, mix the zucchini, onion, garlic, spices and egg together. Stir and add the fish without draining it out of the oil.
Put half of the yellow cheese and stir carefully to prevent the fish from becoming mash. It is good to keep whole pieces of it.
Sprinkle and sprinkle with pepper.
Finally, add the flour mixed with the baking powder. Agitate again and pour the mixture into the mold. Place the remaining cubes of cheese on top. Bake to redness for about 25-30 minutes. Cool and serve with fresh salad. That is all. Enjoy!
