Why not? As more and more people seek after highly nutritious foods, the use of beans might be a unique selling point that stands out in the market. Of course, this cereal had better taste good if it's really going to make a difference. Power O's currently come in strawberry, honey, chocolate and original flavors, and that sounds intriguing. Nutritiously they contain 4-6g of protein per serving, low sodium, and 1.5g fat or less per serving.
I haven't tried Power O's yet. In fact, apart from online sales they don't appear to have wide retail distribution. Nevertheless, when I do get my hands on some I will definitely give them a spin for a review.
