Place the quail in a bowl, then add the soy sauce, pepper, salt, and bay leaf.
Cut the fresh and pickled tomatoes into chunks. Slice the onion into rings.
Add tomatoes and onion.
Cover and marinate for at least 4 hours in the refrigerator.
Preheat the oven to 180°C (356°F).
Pour half of the marinade into the bottom of a baking dish.
Place the marinated quail on top of the marinade.
Arrange the potatoes, zucchini, carrot, fresh tomatoes, green beans, and olives around the quail.
Pour the remaining marinade evenly over the quail and vegetables.
Cover the dish with foil and bake for 40–45 minutes.
Remove the foil and bake for another 15–20 minutes, until the quail is golden and the vegetables are tender.
Remove from the oven and let rest for 5 minutes before serving.
Enjoy your meal!
