If you are wanting to reheat the cooked prawns make sure they are fully cooled and then refrigerate. When ready to reheat; place the chilli garlic prawns on a baking tray and cook in the oven on high for 5 minutes or until sizzling and piping hot (the same method can be used to reheat the courgette). Alternatively, return to the pan and stir fry in a little oil until piping hot. Use your cooked and chilled prawns within 24 hours. If you have bought pre-cooked prawns, follow the packet instructions for heating.
