- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- ½ cup heavy cream or coconut milk (optional)

Instructions
- Preheat your oven to 425°F (220°C). Line a large sheet pan with parchment paper.
- Arrange the halved tomatoes, onion wedges, and garlic head on the sheet pan.
- Drizzle with olive oil and add the tomato paste. Sprinkle with salt, pepper, oregano, and thyme, then toss gently to coat the vegetables evenly.
- Roast for 35–40 minutes until the tomatoes are softened, the onions are caramelized, and the garlic is tender.
