Mix olive oil, garlic, and seasoning in shallow dish. Add shrimp, turning to coat with oil mixture. Let stand at room temperature 15 minutes or refrigerate up to 2 hours. Prepare barbecue (medium-high heat) or preheat broiler. Thread 4 shrimp on each of 4 skewers. Grill or broil just until cooked through, about 3 minutes per side. Sprinkle shrimp with chopped cilantro. Garnish with lemon or lime and serve immediately.
