Prawns: Preheat a grill to moderate high. Place the prawns, bay leaves, chillies and garlic in one large or two medium sized oven proof serving dishes. Pour the olive oil over the prawns and add a little salt and pepper. Place the dish or dishes under the preheated grill. Cook the prawns until they are pink and cooked through 3-5 minutes. Remove them from under the grill and serve.
