Once the pasta is cooking, place olive oil, garlic and rosemary in a large skillet pan over med/low to med heat. Heat just until garlic begins to bubble, about 3-5 mins. Add capers and continue to heat for another 2 mins. Raise the heat a bit, add the tomatoes & simmer just until they begin to fall apart, about 2-3 mins. Add parsley & cook for another couple of minutes.
