01 - Toss the shrimp with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/4 teaspoon black pepper in a medium bowl. Set aside while preparing the sauce.
02 - Combine parsley, cilantro, garlic, extra virgin olive oil, red wine vinegar, oregano, red pepper flakes, 1/2 teaspoon salt, and 1/4 teaspoon black pepper in a separate bowl. Stir thoroughly and let sit for 10 minutes to allow flavors to meld.
03 - Heat a large skillet over medium-high heat. Add the shrimp in a single layer, cooking in batches if needed. Sear for 2 to 3 minutes per side until opaque and lightly golden.
04 - Transfer cooked shrimp to a bowl. Toss immediately with half of the chimichurri sauce while still hot.
05 - Serve the shrimp warm, drizzled with remaining chimichurri sauce. Accompany with lemon wedges if desired.
