Grate the zucchini and mozzarella. Set aside. Take 5 slices of bread.

To make the bread corn katori, cut the bread into circles. Place a round bowl or lid on the bread and press down, then use a knife to remove the edges and set them aside in a separate bowl. The bread will easily come out in a circle. Prepare all the bread in this way.

Spread pizza sauce on one side of the slices. Place the bread in bowls of equal size.

Add some corn, grated zucchini, salt, white pepper powder, and olive oil to the bowl.

Top with grated mozzarella cheese and chili flakes.

Take a baking tray and place all the katoris on it. Preheat the oven to 350°F (180°C) for 5 minutes. Then, place the baking tray on the middle rack of the oven and bake the corn katoris for 10-12 minutes at the same temperature, or until they are golden, crisp, and the cheese has melted.
