1. Heat oil in large skillet over medium-high heat. Add capers, and fry 1 to 2 minutes, or until many capers have split. Remove capers with slotted spoon, and drain on paper towels. Add onion to skillet, and cook 3 to 5 minutes, then stir in garlic and red pepper flakes, and cook 1 minute more. Stir in tomatoes, and cook 5 to 7 minutes, or until tomatoes begin to break down. Stir in 1/2 cup basil and olives, and remove pan from heat.

2. Meanwhile, cook pasta according to package directions. Drain pasta, reserving 1/2 cup cooking water. Add drained pasta to skillet, and toss to combine with sauce, adding some pasta water if mixture seems too thick. Serve garnished with remaining 1/2 cup basil and capers.
