Wash tomatoes and cut in half (if they're large tomatoes, cut into quarters).
Toss tomatoes with remaining ingredients.
Place in a rimmed baking pan or dish. Roast 10-20 minutes or to desired doneness.
Larger or firmer tomatoes such as Romas will need more time (closer to 20 minutes) while ripe small tomatoes such as Campari will only need about 10 minutes. Once cooked tomatoes can sit and be served hot or at room temperature.
