Simple, tasty, adorable treat.
Preheat grill to medium-high heat (350Â° to 400Â°).
Season prawns and calamari.
Max 2.5 min for the prawns for the each side, 2-2.5 min for the calamari also on each side would do the job (overcooking will make seafood chewy and tasteless).
Alternatively you can BBQ but also need to watch closely not to over cook.
