Wash the zucchini.

Cut the zucchini in half lengthwise. Make sure to cut exactly in the middle to prevent leaning on its side while baking.

Spread the tomato sauce on the zucchini evenly according to taste.

Sprinkle the grated Parmesan on top of the zucchinis.

Cut the tomatoes into thin slices and lay them in the middle. Slice the mozzarella, too and add it between the tomato slices. Season with dried oregano.

Place the zucchinis on a baking sheet lined with parchment paper. Bake at 480 degrees F for 15-20 mins until the cheese melts on top.

Leave it to cool for a few minutes then serve!

Good luck preparing it and enjoy!
