Cold dishes are easier to transport because you don't have to worry about losing moisture or heat. However, to keep them cool, purchase an insulated box or bag and fill it with thick cardboard inserts. Sauces and other spillable items will be less likely to spill as a result of this. To keep your meals cold for longer, use dry ice packs. Nice Packs offers long-lasting dry ice packs that may be cut to the size you need.
