Great price for an excellent chip. At about 80 cents for a 2 ounce bag these are a bargain as well as a very tasty chip. Everyone I've let try these has been impressed and commented on how good they taste. I've yet to find a Kettle chip that disappointed!

I'm presently on a diet and I was at my Fresh and Easy Neighborhood Grocery looking over possible diet foods. I wanted things that were tasty, non-fat and low in calories. I came home with about a dozen items. That's how I discovered the Tillen Farms Pickled Crispy Asparagus. Well, I've always liked asparagus anyway and I've enjoyed several brands of pickled asparagus. This Tillen Farms brand is really, really good! It's the best I can recall. There's an excellent flavor and a big clove of garlic down in  the bottom of the jar which I'm looking forward to eating. I can't believe how good this asparagus tastes and right on the front it says "only 60 calories per jar!" Now this is my idea of a good diet food!  Gary Peterson

My personal preference is to stay clear of this. I did not like the smell or taste. I was attempting to make pizza crust for the first time. On my second attempt it came out better, but I did not like the taste of it. If I at least liked the taste, I would buy again and make my crust very thin.
