These are wheat thins, with some flavor added. The Flavor is very salty, and you can definitely taste the MSG that they added as a cheap way to spike the flavor. As far as i remember, you can't really taste the basil at all.

Ex Input:
My dog thinks he was born into the gentry and is entitled to fine dining each evening.  Accordingly, he will not eat plain kibble.  A scoop of this on his dry food, a little water to make gravy and we're good to go.  Ordering a case from Amazon was way easier than picking up individual cans at the pet store, too.  All in all, a success for us.

Ex Input:
The tea tastes great and helped me curb cravings during dieting. The tea was inexpensive and came packaged in a pretty box. The bags are flimsy, but I just throw the bag in a tea ball with no worries. I will continue to keep this on hand as part of my tea collection.
