3) Wrap each prawn and scallop with a half slice of bacon. Wrap each prawn, working from head to tail, pulling bacon snugly around the prawns. Wrap the bacon around the outside of each scallop. Fasten bacon in place as necessary with picks.
4) Arrange the prawns and scallops on a slotted baking pan, such as a grill pan, to allow draining while bacon crisps. Bake prawns and scallops for 10 to 14 minutes, until prawns are pink and curled, scallops are opaque and bacon is crisp. Prawns may finish before the scallops.
Arrange cooked seafood on platter and sprinkle with chopped spring onions.
