In a skillet, heat olive oil over medium heat. Add shrimp and cook until pink and opaque, about 3-4 minutes per side.

In a mixing bowl, whisk together olive oil, lemon juice, oregano, and garlic.

In a large bowl, combine cooked shrimp, cherry tomatoes, cucumber, bell pepper, olives, and feta cheese. Drizzle with dressing and toss to combine.
