01 - Bring a large pot of salted water to a boil. Cook orzo according to package directions until al dente. Drain well, drizzle with 1 tablespoon olive oil to prevent sticking, and set aside.
02 - While the orzo cooks, heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add minced garlic and sauté for 30 seconds until fragrant, being careful not to burn.
03 - Add shrimp to the skillet. Season with salt, black pepper, and crushed red pepper flakes if using. Cook for 2–3 minutes per side until shrimp turn pink and opaque throughout. Remove shrimp from skillet and set aside.
04 - In the same skillet, add halved cherry tomatoes and sauté for 2 minutes until just beginning to soften.
05 - Add chopped spinach, lemon zest, and lemon juice to the skillet. Stir continuously until spinach wilts completely, about 1–2 minutes.
06 - Return cooked orzo and shrimp to the skillet. Toss everything gently to combine all ingredients. Cook for 1–2 minutes until everything is heated through.
07 - Remove from heat immediately. Sprinkle crumbled feta cheese and chopped parsley over the top. Toss gently once more and serve while hot.
