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 shrimp with salt, pepper, and dried oregano, then 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 minced garlic and red pepper flakes for 30 seconds until fragrant. Add halved 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 lemon zest, lemon juice, half of the crumbled feta, and the reserved pasta water. Toss everything together until well combined and creamy.
06 - Return the seared shrimp to the skillet and gently toss to combine. Serve warm, garnished with the remaining feta and fresh parsley.
