Slice off the tops of tomatoes and carefully scoop out the pulp. Keep the pulp for later.
Heat olive oil in a pan. Sauté onion and garlic until soft.
Add rice, tomato pulp, herbs, salt, pepper, and oregano. Stir well.
Pour in water/broth and simmer for 5–7 minutes (rice should be slightly undercooked).
Fill each tomato with the mixture (leave a little space for rice to expand). Place tops back on.
Arrange in a baking dish, drizzle with olive oil, and bake at 180°C (350°F) for 45–60 minutes until tender.
Let cool slightly before serving—flavors deepen as it rests.
