Martha created this simple puttanesca recipe in response to a TV viewer's request for easy meals to prepare with household ingredients.
Bring a large pot of water to a boil. Generously salt boiling water and return to a boil. Add pasta and cook according to package directions. Drain.
Meanwhile, heat oil in a medium skillet over medium heat. Add garlic, red pepper flakes, and anchovies, if desired, mashing with a wooden spoon. Cook, stirring, until garlic is fragrant, about 2 minutes.
Add tomatoes and their juice, breaking up tomatoes with hands. Stir in capers, if desired, and olives. Bring to a boil and immediately reduce to a simmer. Let simmer until thickened, 5 to 10 minutes. Add pasta to skillet and season with salt and pepper; toss to combine, and serve.
