Baked Zucchini with Mozzarella and Tomatoes

Preheat the oven to 200–205 °C and prepare a baking dish (approx. 25 cm × 30 cm). Peel the onion and cut it into coarse cubes along with the zucchini and bell pepper. Halve the cherry tomatoes.

Place the prepared vegetables in the baking dish. Add oregano, olive oil, garlic powder, and salt and pepper, then mix everything well.

Place the dish in the preheated oven and roast the vegetables for 20–25 minutes.
