Example Input: Yes, tasty -- but it takes a little getting used-to.  You have to like coconut to like this snack item.  That taste quite overwhelmed all else, for me.  I found few chocolate chips -- maybe they were all taking a rest when my snacks were baked.  Anyway, it's a chewy but tasty item worthy of your consideration.  Give it a try.
Example Output: 3

Example Input: I ordered these because I had purchased a bag of Sweet maui Onion chips from the supermarket. They were so good that I had to get another.  The order came and I popped open a bag. They are very crunchy, so if you're into that, these are the chips for you. However, they do tend to get really salty. I found myself having quite a few sips of beer when eating these

Example Input: If you are looking for a sweetener that is delicious in tea, Stevia can be used to sweeten hot or cold tea. You can almost say goodbye to regular sugars in your drinks once you get a taste for the Stevia powder.  Unlike artificial sweeteners, Stevia is never bitter and won't leave a nasty aftertaste in your mouth. The packets are easy to carry with you and you may even notice you have less cravings for sugary foods.  By using a low calorie (0 Calories) sweetener with only 1 gram of carbs, you will be ahead of the game. Every single time you use one packet of Stevia, you are using less sugar and you won't even miss it.  ~The Rebecca Review
