Preheat the broiler. Position the rack 4 inches from the heat source. Cover a broiler pan or cookie sheet with aluminum foil. Spray generously with cooking spray.
In a large bowl, whisk together the honey, lime juice and oil. Add the scallops and toss gently to coat with the honey mixture.
Arrange the scallops in a single layer on the prepared broiler pan or baking sheet. Broil until opaque throughout when tested with a tip of a knife, about 5 minutes. Turn the scallops over and broil for another few minutes until just turning brown.
Pour any juices from the broiler pan or baking sheet over the scallops. Sprinkle with grated lime peel and serve with a lime wedge.
