01 - Bring a large pot of salted water to a boil. Cook orzo according to package instructions until al dente. Drain, reserving 1/2 cup of pasta water, and set aside.
02 - While the orzo cooks, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the shrimp with salt, pepper, and dried oregano. Cook for 2 to 3 minutes per side until pink and opaque. Transfer to a plate and set aside.
03 - In the same skillet, add the remaining olive oil. Sauté the garlic and red pepper flakes for 30 seconds until fragrant. Add the cherry tomatoes and cook for 2 to 3 minutes until softened.
04 - Stir in the chopped spinach and cook for about 1 minute until just wilted.
05 - Add the drained orzo to the skillet along with the lemon zest, lemon juice, half of the crumbled feta, and the reserved pasta water. Toss well until everything is evenly coated and creamy.
06 - Gently fold the cooked shrimp back into the skillet and toss to combine with the orzo mixture.
07 - Serve warm, garnished with the remaining feta cheese and freshly chopped parsley.
