The semi-roasted tomatoes are best eaten as soon as they are made.
Preheat the oven to 450°F.
Place the vines of tomatoes on a heavy baking sheet. Scatter the thyme sprigs over. Drizzle the oil over the tomatoes then sprinkle the tomatoes with salt and pepper.
Roast the tomatoes in the oven for 8 minutes, or until they are heated through.
