In a large skillet, heat oil over medium-high heat.
Add the garlic and stir for a minute to develop the flavor. Add shrimp to the skillet and saute for 2 minutes.
Add artichoke hearts, feta cheese, tomatoes, olives, lemon juice, parsley, oregano, salt, and pepper.
Saute for 2 minutes or until shrimp are cooked and pink.
Meanwhile, cook pasta in large pot of boiling salted water until just tender but still firm to bite, stirring occasionally. Drain. Transfer pasta to large bowl.
In a large bowl, stir together the pasta and shrimp mixture; toss to coat.
Season with more salt and pepper if needed and serve.
