Meat and vegetables, the staples of a Paleo diet, aren't easy to tote around for a convenient snack when hunger strikes. But with a lot of research and testing, it's possible. Example one: Wild Zora Beef and Veggie Bars do just that. These bars are shelf-stable, meaning they don't need to be refrigerated. Throw them in your purse or backpack and be on your Paleo way. They come in many flavors, but we sure do like this barbecue flavor, which tastes of hickory and tomatoes.
