01 - In a medium bowl, whisk together olive oil, lemon juice, lemon zest, minced garlic, salt, pepper, and red pepper flakes until well combined.
02 - Add shrimp to the marinade, toss to coat evenly, and refrigerate for 10-15 minutes to allow flavors to penetrate.
03 - Preheat grill or grill pan to medium-high heat, approximately 375-400°F.
04 - Thread marinated shrimp onto skewers, placing about 5 shrimp per skewer and leaving slight space between pieces for even cooking.
05 - Grill shrimp skewers for 2-3 minutes per side, turning once, until shrimp are opaque and slightly charred with grill marks.
06 - Remove from grill, sprinkle generously with chopped parsley, and serve immediately with lemon wedges on the side.
