Cheese and crackers is a classic combination that contains protein with whole-grain, good-for-you carbohydrates, keeping your hunger satisfied for the long-haul. Prep cheese slices at home or throw a few single-serving string cheese snacks into a cooler, and separate your favorite crackers into single-serving portions ahead of time to make this snack car-friendly. You can even pull this combination together at a convenience store, in a pinch.
Looking for something that combines both salty and sweet? Try swapping the cheese on your cracker for peanut butter (or another nut butter if you're concerned about peanut allergies) or apple slices for healthy alternatives that are good sources of protein, fiber and vitamins.
