Example Input: I thought I was doing my kid a favor when I invested in a case of Earth's Best dinners.  Unfortunately, the second ingredient (after water) for all of these is....applesauce.  Or in the case of the "Sweet Potato & Chicken" variety, it's sweet potatoes, followed by apricot puree.  After getting used to the sweetness of these (try 'em - they're like jam), it's difficult for kids to adjust to "real" food.  From now on, I'm going to stick with just pureeing home-cooked food.  It's a lot cheaper, too.

Example Input: Newman's Own Organics Lamb and Barley New Zealand Ranch Style Dog Treats, 10-Ounce (Pack of 6) were not enthusiastically welcomed by our two dogs a terrier mutt and a German shepherd.  Both dogs were kind of suspicious when I handed them their Newman's Own Organics Lamb and Barley New Zealand Style Dog treats in their 10 ounce pack of 6.  Maybe the treats were too dry.  Later the dogs munched on them politely I think to not hurt my feelings.  I tried them (Newman's Own Organics Lamb and Barley New Zealand Style Dog treats) and found them to be delightful with a shot of brandy.

Example Input: I don't think these coffee bags are as good as fresh ground fresh brewed coffee, but they taste far better than instant coffee.  At work, we have a water cooler with hot water dispenser.  This brewed in hot water just like a tea bag making tea tastes far better than any instant coffee.  I highly recommend it to any coffee lover when you have access to very hot water but don't have access to a coffee maker.  Individual wrapped and sealed bags allow you to take one tiny tea like bag with you in your pocket or purse to your early morning meetings.
