Cook spaghetti in boiling salted water according to directions on package. When pasta is nearly finished heat olive oil in a small skillet or saucepan over medium-low heat. Add garlic and saute until just lightly golden, about 1 minute. Drain pasta and pour into a large serving bowl or mixing bowl. Pour olive oil and garlic mixture over pasta. Add in tomatoes, olives, feta, capers and parsley.
