Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.

Example Input: I love Panang Curry but would rather avoid the white rice that most restaurants serve with it. So decided to try making my own, and with this product, I get exactly what I want, hot tasty Panang Curry adding lots of fresh veggies, tofu and brown rice. And it's very hot, didn't have to add any spices at all. Great product, will purchase again.
