In a saut? pan or heavy frying pan, warm the olive oil over medium heat. Add the red pepper flakes, and garlic and saut? for about one minute or until they begin to brown.

Raise the heat to high and add the shrimp, lemon juice, sherry and paprika. Stir well, then saut?, stirring briskly until the shrimp turn pink and curl ? about 3 minutes.

Remove from heat and transfer shrimp with oil and sauce to a warm plate or serve right from the pan. Season to taste with salt and freshly ground black pepper. Sprinkle with parsley.
