1. Trail Mix: Make your own by combining 2 parts nuts with one part no-sugar-added dried fruit and put a 1/3 cup serving in a plastic baggie. Or try one of the new pre-packaged options that are already portioned out.

1. Apple and Peanut Butter: Yes, you can take this with you! Apples do not have to be refrigerated and travel very well. Many companies now sell single-serving packages of peanut butter, which make them very easy to throw in your purse.

1. Lean Beef Jerky and Unsweetened Apple Sauce: This makes for a great sweet and salty combination. Individually-wrapped beef jerky and single serving containers of apple sauce make this an easy snack to keep anywhere- even in your purse.

1. Tuna Snack Packs: I found these at the grocery store in the aisle with the regular cans of tuna. These snack packs come complete with a single-serving packet of tuna, some light mayo, relish, and whole wheat crackers. I often take them in the car on road trips for a filling snack.

1. Popcorn with Dried Roasted Chickpeas: You can find roasted, dried and seasoned chickpeas in specialty grocery stores or you can make your own- add it to some pre-popped popcorn for a flavor, crunchy snack.

1. Almond Butter and Banana Sandwich on Whole Wheat Bread: Don't just think of sandwiches as lunch fare-options such as this can make great snacks as well. I cut my sandwich into fourths before packing it up so that I can just eat the amount I need. This is good for a day of driving too as one sandwich can serve as 2 or 3 snacks.

1. Carrot Sticks and a Wedge of Laughing Cow Cheese: If you will be eating your snack in less than 4 hours, this snack works as a portable option as these things can stay unrefrigerated just fine for about that long. If it is going to be longer than that, or you would like to be able to take more fresh options with you, simply get a small cooler with ice packs to keep in your car to keep the food cool.

1. Snack Bars: Choose ones that contain a combination of carbohydrates and protein, such as Luna bars, Kind bars, and Lara bars. I always keep one of these in my gym bag and purse.

1. Dry Whole-Grain Cereal mixed with Sunflower Seeds: This is a great option that you can seal in a plastic baggie and keep in your purse or desk drawer for several weeks. Use 2 parts cereal and 1 part seeds and limit total serving to 1/3 cup.

1. Rice Cake with Low-fat Pudding Cup: If you are craving something sweet on the go, this snack is a great option. Choose a pudding cup that doesn't require refrigeration and pair it with a whole grain rice cake for a snack that is a good source of calcium and also provides a little protein and fiber.
