01 - Bring a large pot of salted water to a boil. Cook orzo according to package directions 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 2-3 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 2-3 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 everything together until well combined and creamy.
06 - Gently fold the cooked shrimp back into the skillet. Serve warm, garnished with the remaining feta and fresh chopped parsley.
