How to Make It
In a large pot of boiling salted water, cook the pasta until al dente. Reserve 1/2 cup of the pasta cooking water. Drain the pasta and return it to the pot.
Meanwhile, heat the olive oil in a medium skillet. Add the crushed red pepper and cook over low heat, stirring, for 2 minutes. Add the garlic and cook until fragrant, about 2 minutes. Stir in the tomatoes and cook over moderate heat for 3 minutes. Season with salt. Add the shrimp and cook until they turn pink and begin to curl, about 3 minutes. Stir in the olives and reserved pasta cooking water and cook until the sauce thickens slightly, about 2 minutes. Season with salt and pepper. Toss the pasta with the sauce and parsley to coat, transfer to a warmed bowl and serve.
