1) Bring a large pot of salted water to the boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes.
2) Drain pasta and put the pasta on a large baking tray. Drizzle the pasta with 3 tablespoons olive oil, toss, spread out, and set aside to cool.
3) Once the orzo is cool, transfer to a large serving bowl. Add the remaining ingredients and toss gently to combine. Serve.
