Heat oven to 400 degrees F. Oil a shallow 3 quart baking dish. Cut the tomatoes in half through the equator and arrange, cut-side up, in the prepared baking dish. Drizzle with the vinegar, then season with 1/2 teaspoon salt and 1/4 teaspoon pepper. In a medium bowl, combine the bread crumbs and cheese, then the oil. Toss with the garlic, basil, and thyme. Sprinkle the crumb mixture over the tomatoes. Bake, covered, for 25 minutes. Uncover and bake until the tomatoes are tender and the bread crumb mixture is golden brown, 10 to 12 minutes more. Sprinkle with additional basil, if desired.
