That is right, open the bag and just get your nose close and smell it. You know this is a quality product instantly. Some of the tastiest tea I have had and the Oolong and orange are a great mix. Even if you aren't a tea drinker at all, once you smell this tea you will want to try it. I am very glad I bought this product it is a favorite of mine.

My husband refuses to eat fish, but he LOVES this. It only takes 10-12 minutes to make, and is way better than any other kind of Tuna Helper I've tried.  Besides the box itself, you'll need:   - 1 can of tuna (6 oz., or I use 8 oz.)  - 1 tablespoon of butter  - 1 cup of milk  It's a breeze to prepare, just DON'T leave it alone before you put the tuna and pasta in. Because of the milk, it likes to boil over. Just keep an eye on it and reduce the heat right after it starts boiling.

My husband and I went Gluten Free earlier this year due to a health condition.  We stumbled across this product at Whole Foods and decided to try it.  These were incredible...  so cheesy and spicy!!!  So much so, we decided to buy a case on Amazon.  Once our original case was depleted, we re-ordered, and though the product looks identical, the new case contained cheese curls with little to no seasoning.  They were so bland that we had no desire to eat them.  We opened each bag in the case hoping some of them would be good like the first case we purchased, but to our dismay, we ended up tossing the entire case.  We will not be buying these again.  What a letdown...
