Example Input: I purchased these because they do not contain dairy, soy or corn.  Well, in addition to being dairy free, soy free.... they are FLAVOR FREE!  Absolutely horrible dry tasting bars.

Example Input: I love this pancake mix. Can not find this exact one in any stores so I always order online and keep in stock at home. All you do is mix with water (I add fresh chopped banana's or strawberries for a healthy option, and swap syrup for honey) and cook in a lil butter and you have an awesome breakfast.
