Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes. Drain pasta and put the pasta on a large cookie sheet. Drizzle the pasta with 3 tablespoons olive oil, toss, spread out, and set aside to cool.

Once the orzo is cool, transfer to a large serving bowl. Add the remaining ingredients and toss gently to combine. Serve.
