My job requires frequent travel and I like to eat healthy foods without the expense of restaurant food or the ingredients used in that food so I prepare meals in advance, seal them in Foodsaver bags (purchased by the roll so I can choose the size), and freeze the bagged contents.

When I'm ready to travel, I pack the frozen food in an insulated bag and take along enough food to last 2 or 3 days, which I store in the refrigerator at the hotel.

Foodsaver bags are durable and keep the food fresh.
