Finger foods are the ticket to a healthy lunch on the go.

The Game Plan

A homemade turkey wrap (recipe, below) beats goopy plane food any day. At the supermarket, buy:

Sugar snap peas or steamed edamame

Crackers and firm cheese (such as Swiss, Cheddar, or Muenster)

Fruit (such as apples, pears, and grapes)

Chocolate bars

Tip: Brown-bagging a meal lets you arrive refreshed and can save you money, too (food-court snacks add up quickly). Airport security bans passengers from bringing more than three ounces of liquid from outside the terminal. Once you’re past the checkpoint, buy some bottled water at a newsstand.
