Preheat the oven to 180°C and grease a baking dish with 1 tbsp olive oil. Cut the cherry tomatoes in half lengthwise and place them in the baking dish, cut side up.
Peel and crush the garlic, then mix with the honey, olive oil, Italian seasoning, freshly ground black pepper and coarse sea salt to taste.
Brush the tomatoes with the olive oil and honey mixture and scatter fresh thyme over the top.
Roast in the oven for 40 minutes, until the tomatoes are soft and juicy.
