Even for the most frugal professional, the cost of going out for lunch every day quickly adds up. Even if we keep each check under $10, our monthly tab will still flirt with the $200 mark. And it doesn't take a calculator to figure that after a year, we've spent somewhere in the neighborhood of $2,000 on our midday meals. There's a better way. Employees who bring a packed lunch from home estimate they reduce the cost of their lunches by at least 50 percent. And arguably, the food they bring from home is healthier—and less fattening—than that they'd get at the corner diner. Who doesn't want to cut costs and lose weight at the same time? But before you start packing tomorrow's vittles, take a moment to consider your container. Those brown paper bags, aside from being slightly depressing, are tough to reuse. And metal mailboxes sporting superheroes just aren't appropriate for the office cafeteria. Instead, choose from a variety of reusable nylon lunch carriers that look professional and fit conveniently into the office refrigerator. Here are a few of our favorites.Super LunchboxThis nylon lunchbox looks like a mini backpack, and it's made out of the same material. Insulated pockets keep food cool, a smaller front compartment keeps chips and other items safe from being crunched, and the bag, available in five colors, can even be monogrammed. $15.00 www.llbean.comTechWeave Lunch CoolerThis grown-up version of the lunchbox features a leak-proof liner with a mesh pocket on the inside lid for smaller items.
