Quit turning to cocktail weiners every time you go to throw a party and make these elegant, and better for you, prosciutto-wrapped peppers, instead.
Whisk together the olive oil, vinegar, and salt and pepper, to taste. Add the peppers and marinate for 1 hour. Fill each pepper with a piece of mozzarella. Wrap a slice of prosciutto around each pepper. Top each with a basil leaf and olive, held together with a toothpick.
