Pita Pocket
More of a meal than a snack, pack a whole wheat pita with lettuce, turkey, and cheese. Skip the onions, to save your seatmate from your breath; no avocadoes, which quickly brown; no mayo, to save you a trip to the emergency room after it’s been at room temp for awhile; no tomatoes, which make the bread soggy. The protein from the cheese and meat will keep you energized, and the fiber from the whole wheat and lettuce will keep you feeling full.
