Spicy Lime Shrimp Kabobs

2 limes, zested and juiced
2 green chile peppers, seeded and chopped
2 cloves garlic, minced

Place the prawns and lime zest in a large zip lock bag. In a food processor, add the olive oil, lime juice, chile pepper, garlic, ginger, and onion. Process until smooth. Pour marinade in the bag of prawns, massage to coat. Cover, and refrigerate for 2 hours.

Preheat grill for medium-high heat. Thread prawns onto skewers, piercing each first through the tail, and then the head. Cook prawns for 5 minutes, turning once, or until opaque.
