Yummy prawns and vinaigrette! A lot of work but worth it! ;-)
Place the prawns and lime zest in a large glass or plastic bowl.
Place the lime juice, chili pepper, garlic, ginger, and onion in a food processor or blender and process until smooth. You may need to add a little oil to assist in blending. Pour over the bowl of prawns, and stir to coat. Cover and refrigerate for 4 hours.
Preheat grill at medium high. Thread prawns onto skewers by piercing each first through the tail and then the head.
Brush grill grate with oil. Cook prawns for 5 minutes, turning once, or until opaque.
