Instructions:

1. Preheat Oven:
Preheat your oven to 275°F (135°C). This low temperature is key to gently roasting the tomatoes and bringing out their natural sweetness.

2. Prepare the Tomatoes:
- Wash the tomatoes thoroughly.
- Cut each tomato in half lengthwise.
- Place the tomato halves cut side up on a baking sheet lined with parchment paper for easier cleanup.

3. Season the Tomatoes:
- Peel and finely chop the garlic cloves.
- Sprinkle the chopped garlic evenly over the tomatoes.
- Drizzle the tomatoes with olive oil, ensuring each tomato half gets a bit of oil.
- Sprinkle the brown sugar over the tomatoes. This will help caramelize the edges and enhance the tomatoes' natural sweetness.
- Finally, drizzle the vinegar over the tomatoes for a touch of acidity that balances the flavors.

4. Roast:
- Place the baking sheet in the preheated oven.
- Slow-roast the tomatoes for approximately 2-3 hours. The exact time may vary depending on the size and ripeness of your tomatoes. They should be shrunken and slightly caramelized around the edges but still juicy in the middle.
- Check occasionally to ensure they are caramelizing, not burning.

5. Cool and Serve:
- Once roasted to your satisfaction, remove the tomatoes from the oven and let them cool slightly.
- Serve immediately as a side dish, on top of salads, or as part of a pasta dish. They can also be stored in an airtight container in the refrigerator for up to a week.

These slow-roasted tomatoes are a versatile and delicious addition to many meals. With just a handful of ingredients and some patience, you can create a deeply flavorful and naturally sweet component that enhances any dish.
