Fill a lunch thermos with boiling water and let it sit while preparing the potato and toppings.
Reheat Potato
Reheat potato in the microwave for 1-2 minutes or until steaming hot. Cut it into pieces and add it to the preheated thermos. Layer on your hot toppings and close the lid.
Pack Toppings
Store cold or additional toppings in small leak-proof containers.
Pack for School
Place the thermos in a lunch bag, keeping it apart from the cold toppings and any chilled lunch sides. Add an ice pack to the cold items and remember to include a fork.
