Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>

My son loved all the sauces. The only sauce that was way too hot was the Insanity Sauce, use a teensy tiny bit when using.

I've found a new taste treat. I'm not a big one for potato chips, so I am sure I've come late to discover these. I think they are really good. The processing & ingredients list is actually pretty good-no trans fats, etc. So, if you want an indulgence, these are A+ ! They are thicker & more tasty than the mass produced potato chips we've all come to know. They are much more flavorful. Never had a honey-dijon potato chip before. Incredibly good & a flavorful combination of sweet, tangy, salty. Also not overly hot or spicy. Excellent! If you want a snack, have something REALLY good. It's got to be worth the calories-and these are!
