Pasta with Roasted Tomatoes and Capers

1. Preheat oven to 450°(F). On a rimmed baking sheet, toss tomatoes, capers, and oregano with oil and season with salt. Roast until tomatoes burst and begin to brown, 25 to 30 minutes. Meanwhile, in a large pot of boiling salted water, cook pasta according to package instructions. Reserve 1/2 cup pasta water, then drain. 2. Return pasta and 1/4 cup pasta water to pot and add tomato mixture. Add tomato sauce to pan. Cook over high until sauce is slightly thickened, 3 to 4 minutes. If necessary, add remaining pasta water to create a light sauce that coats pasta. Serve sprinkled with oregano and topped with parmesan.
