Combine pasta, tomatoes, onion, garlic, red-pepper flakes, basil, oil, 2 teaspoons salt, 1/4 teaspoon pepper, and water in a large straight-sided skillet. Bring to a boil over high heat.

Season to taste with salt and pepper, divide among 4 bowls, and garnish with basil. Serve with oil and Parmesan.
