I prefer the 100-Calorie Ziplock Snack Bags because they promote portion control. I love to fill the bags with cereal! I buy Kashi GOLEAN (14.1 oz) and Peanut Butter Captain Crunch (15 oz). AS SOON as I get home, I mix the dry cereals together, and portion them in the 100-Calorie Ziplock Bags. It usually fills 16 bags, lasting me 2-3 weeks. With just 175 calories per bag, I can add one serving of fruit for a great snack on the go!
You can find this in the Nutrition Tracker under: Kashi GOLEAN & Captain Crunch Peanut Butter (16 Bag Portion)
You don't have to use the cereals I chose, but I strongly suggest that you add Kashi GOLEAN. I also do this with cashews, but you have to be careful! Nuts pack a TON of calories.
