Bring a medium sized pot of salted water to a boil. Add orzo and let boil for 9 minutes.
Meanwhile, prep tomatoes, olives, cucumbers, and onion and add it all to a large bowl.
Create dressing by adding oil, lemon juice, garlic, oregano, salt, and pepper to a dish (like a spouted pyrek) and whisk vigerously with a fork.
Once the orzo is done, drain and add to large bowl with veggies.
Mix well and then add dressing. Mix well again. Top with fresh parsley and feta and give a final mix.
Serve immediately, or store in fridge until ready to serve.
