01 - In a medium bowl, toss the shrimp with 1 tablespoon olive oil, salt, and black pepper. Set aside.
02 - In a separate bowl, combine parsley, cilantro, garlic, olive oil, red wine vinegar, oregano, red pepper flakes, salt, and black pepper. Stir well and let sit for 10 minutes to meld flavors.
03 - Heat a large skillet over medium-high heat. When hot, add the shrimp in a single layer, working in batches if necessary. Sear for 2–3 minutes per side, until opaque and lightly golden.
04 - Transfer the cooked shrimp to a bowl. Toss immediately with half of the chimichurri sauce.
05 - Serve the shrimp warm, drizzled with extra chimichurri sauce and lemon wedges if desired.
