Method:
Put tomatoes, garlic, brie, oil, vinegar, salt and pepper into a large bowl and toss gently to combine. Cover and set aside at room temperature to let marinate for 2 to 3 hours.
Bring a large pot of salted water to a boil. Add penne and cook until al dente, about 10 minutes. Drain well and transfer hot pasta to bowl with tomato mixture. Add basil and toss gently to combine. Serve immediately.
