Cook the linguine according to the package directions. Meanwhile, heat the oil in a large skillet over medium heat. Season the shrimp with the pepper and cook until they begin to turn pink, about 2 minutes. Turn the shrimp, add the capers, olives, and anchovies (if using), and cook for 2 minutes more. Add the marinara sauce and cook until heated through, about 4 minutes. Divide the drained pasta among individual bowls and spoon the shrimp and puttanesca sauce over the top.
Excellent and super easy to make. I added some crushed garlic to the olive oil. Next time I will use less olives and 3 or 4 anchovies. You can't really taste the anchovies but they add a nice flavor even if you ordinarily don't like them.
