My son really enjoys Earth's Best lentil!  He eats the entire jar for dinner and always wants more.  The product shipped very quickly.

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

As an Oregonian, I make a point of sharing these Oregon-made snacks with friends who visit the state. I tell them the Kettle Brand does for potato chips what microbrew does for beer.  Kettle Brand potato chips are unmistakable--a light gold color, rich flavor and amazing crunch. Kettle Brand chips are also a healthier snacking option than the major chip brands. Kettle Brand chips don't have trans fats, MSG or artificial flavors and colorings. The company also has a line of organic potato chips and all of their products are certified Kosher.  Annette Solomon, a reporter for the Salem Statesman Journal noted that a glass of wine goes nicely with Spicy Thai chips. Solomon wrote, "...you could be missing out on a wonderful pairing. These chips are spicy, so you would want to select a semi-sweet white wine. Also, a moderate amount of acid will subdue the strong flavors of ginger, lime, garlic and cilantro without over-powering them. Classically, a German-style Riesling fits these parameters perfectly."  I also recommend <a href="http://www.amazon.com/gp/product/B000G6MBV4">Kettle Chips Honey Dijon</a> and <a href="http://www.amazon.com/gp/product/B000G6MBUA">Kettle Chips Sea Salt & Vinegar</a>.  The Honey Dijon chips bring a terrific balance of salty, tangy, sweet and crunchy. Other brands I've tried use too much mustard flavor, which overpowers the Honey Dijon pairing. The Honey Dijon chips make a great side dish on a BBQ plate with baked beans, coleslaw or potato salad and grilled meat. Naturally, they also go down great with beer.  The Sea Salt & Vinegar chips are a perfect complement to vegetable trays of cucumber, carrot, celery and cherry tomatoes. Skip the dip; balance the tangy chips by alternating bites of raw vegetable.  In summary, I highly recommend Kettle Brand chips, a great buy on Amazon.com.
