I've tried one of these in a salted caramel flavor and can confirm they are tasty and keep you full for a few hours.
Promising review: "With a name like Perfect Bar you have to be a bit skeptical of the product. I have to say that I was not disappointed. This is a refrigerated whole food product. It is refrigerated to keep it fresh and extend the shelf life. There are no preservatives, artificial ingredients or anything else to keep these shelf stable for an extended period of time. So what is in these? Nothing bad. Organic everything, well nearly everything. The first ingredient is organic peanut butter followed by organic honey, milk and egg powder, organic- rice protein, flax seed oil, sunflower seed oil, sesame seed oil, olive oil, pumpkin seed oil (all organic), and a really interesting mix of organic dried whole foods (these must be the super foods) kale, flax seeds, rose hip, orange, lemon, papaya, tomato, apple, alfalfa, celery, kelp, dulse, carrot, and spinach. I use these for meal replacement, a snack, after workout boost, and breakfast on the go. They travel well and will keep for several days warm. Highly recommended as a quality made, delicious tasting, guilt-free, nutrition option." —Jeff K.
