Cut the shrimp in half lengthwise.
Heat the oil in a medium skillet; add the onion, garlic, and shrimp,
and sauté the ingredients, stirring, until the shrimp turn pink,
about 5 minutes. Remove the shrimp from the skillet; set them aside.
Add the tomatoes and juice, black pepper, cayenne, basil, and
salt to the skillet. Bring the mixture to a boil, reduce the heat,
and simmer it, uncovered, for 5 minutes. Add the shrimp and parsley
to tomato mixture, and serve the sauce over spaghetti or other
pasta garnished with olives and sprinkled with Parmesan, if desired.
