Box Lunch on NCL Gem

Taking a family cruise next June on NCL Gem and wondered if anyone has ever requested a box lunch while in port at Nassau Bahamas. Looking at trying to book two tours and not much time for lunch between the town tour and dolphin swim. Any suggestions or does anyone know if requesting a box lunch is an option?

Thanks in advance for any suggestions
Okay folks - already found my own answer! As I already thought and told my daughter the answer is no due to many countries not allowing food/fresh fruit into their country. Guess they will take one less tour and maybe meet us at Senor Frogs!
