Roasting gives these little tomatoes extra flavor when tossed with the olive oil and spices.
Preheat oven to 450 degrees. On a rimmed baking sheet, toss tomatoes with thyme or oregano, olive oil, and garlic, if using; season with salt and pepper. Roast until tomatoes are very soft and skins have split, 8 to 10 minutes. Serve with crackers or crostini.
