For an extra layer of flavor, consider adding a pinch of red pepper flakes to the shrimp while cooking. Freshly grated Parmesan cheese makes a wonderful garnish. If you prefer to make your own pesto, blend fresh basil leaves, pine nuts, garlic, Parmesan cheese, and olive oil in a food processor until smooth. Ensure not to overcook the shrimp, they are best when tender and juicy.
