01 - In a large bowl, whisk together the olive oil, lemon juice, lemon zest, minced garlic, chopped chili, smoked paprika, sea salt, and black pepper until well combined.
02 - Add the peeled and deveined shrimp to the marinade, tossing to coat evenly. Cover the bowl and refrigerate for at least 20 minutes, or up to 1 hour for deeper flavor penetration.
03 - Preheat an outdoor grill or grill pan over medium-high heat. If using wooden skewers, soak them in water for at least 20 minutes beforehand to prevent burning.
04 - Remove the shrimp from the marinade and thread them onto skewers, distributing evenly. Discard any remaining marinade.
05 - Place the skewers on the hot grill and cook for 2 to 3 minutes per side, turning once, until the shrimp are pink, opaque throughout, and lightly charred on the edges.
06 - Transfer the grilled shrimp to a serving platter, garnish with chopped fresh parsley and lemon wedges, and serve immediately while hot.
