Bring a large pot of lightly salted water to a boil. Add orzo and cook for 8 to 10 minutes or until al dente. Drain and set aside.
Place basil leaves and sun-dried tomatoes in a food processor. Pulse 4 or 5 times until blended.
In a large bowl, toss together the orzo, basil-tomato mixture, olive oil, Parmesan cheese, salt and pepper. Serve warm or chilled.
