Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper. Arrange the zucchini rounds on the tray, brush both sides with olive oil, and lightly season with salt and pepper.

Bake the zucchini for 5-7 minutes until they soften slightly but remain firm enough for toppings. Take them out of the oven and spread a thin layer of natural tomato sauce on each slice. Sprinkle with a pinch of dried oregano, basil, and garlic powder for flavor.

Top each slice with crumbled feta cheese and return them to the oven. Bake for another 5-7 minutes, or until the cheese melts slightly and the zucchini edges turn golden.

For a final touch, add fresh basil leaves if desired, and serve these warm, healthy Zucchini Pizza Bites as a tasty snack or appetizer.
