01 - In a medium mixing bowl, whisk together olive oil, lemon juice, lemon zest, minced garlic, oregano, red pepper flakes, salt, and black pepper until well combined.
02 - Add shrimp to the marinade and toss to coat thoroughly. Cover the bowl and refrigerate for 10 to 15 minutes, ensuring the shrimp do not over-cure.
03 - Preheat grill or grill pan to medium-high heat. If using wooden skewers, soak them in water for at least 20 minutes before threading.
04 - Carefully thread marinated shrimp onto skewers, placing 4 to 5 shrimp per skewer, leaving small gaps between each piece.
05 - Place shrimp skewers on the preheated grill and cook for 2 to 3 minutes per side until shrimp are pink, opaque, and show slight charring.
06 - Transfer grilled skewers to a serving platter, garnish with fresh chopped parsley, and serve immediately with lemon wedges.
