Big-O

It's got a higher fat and sugar content than most and what I usually prefer, but then again, it has real ingredients that can be pronounced and not cheap fillers it seems can be found in protein bars. The peanut butter and fruit cereal are an incredible combination, I'd definitely keep coming back.
