Don't know about zone bars at home, but I just found this great new low carb snack - they are these fun little muffin balls! They are called Almond Butter Boulders and only have 3 net carbs. They are soooo good. I know you can buy them at www.nutballz.com, but I don't know if they are available in stores yet. Has anyone else been able to try them?
