Cut the tomatoes in half end-to-end, and place cut side up on a pan.
Optional: Slice 4-5 cloves of garlic, and sprinkle over the tomatoes.
Strip several sprigs of fresh thyme, and sprinkle the leaves over the tomatoes.
Season with sea salt and fresh ground black pepper and drizzle extra-virgin olive oil liberally over all of the tomatoes.
Place in the oven at 200°F for 6-8 hours; the tomatoes will collapse, but not completely dry out. (since they’ll be in there a while, preheating is not necessary)
Cool and serve with crackers and soft cheese or package to preserve.
