Place the chopped tomatoes, capers, garlic, olive oil and basil in a large bowl. Add salt and pepper to taste. Let marinate for at least an hour.
Cook the pasta. Bring a large pot of water to boil. Generously salt the water and cook the pasta to al dente. About 1 minute less than the package directions. Drain and add to bowl of tomatoes. Let pasta salad sit at room temperature for at least another hour, if not more. Pasta will soak up the juices.
Before serving, adjust to taste with more olive oil, salt and fresh cracked pepper. Serve at room temperature.
